Crossing the Wine-Dark Sea: Journeys Through Ancient Literature by Emily Wilson
I have heard that in Japan, translators are well known and respected almost as much as authors. In the English speaking world, they are almost treated as an afterthought. However, translators play a huge role in how we experience works of literature. This can be especially important with ancient works. Most of the popular Greek works of today were experienced as popular culture. They were in the vernacular of the day and would be more akin to a superhero movie than work of literature. Alas, we often experience them in archaic translations. This causes a barrier to their understanding. Translators also struggle with the feel of the work. One word may be translated exactly with a 30 word phrase, but then you've lost the flow. A single word may be better even if it is not exact. How do you get the rhythm and meter in different languages? What about slang and scatalogical language? And what about different dialects present in the original?
In this book, the author explores her experience with different ancient works and the art of translation. It is filled with interesting examples of trade offs made in translation and how she feels about it. I would love to see more translated works accompanied by a discussion from the translator.
The concluding book of the Titans series ramps up the stakes. The bad guys are set to not only take over earth but all planets in the universe. Their "home" planet is actually a planet that was occupied by another group before. There are various skirmishes and a unified plan by Titans, Greeks and others. However, odds were not looking good. Then the book suddenly came to a conclusion. The queen was killed, then all of the others started to fight for dominance. The "friendly" daughter ended up becoming queen and suddenly all the mimics stopped and world peace was in place. 
The middle Titans book continues with escalating stakes. The mimics have infiltrated earth and are set on planetary domination. There are many cases of travel through the solar stream. It is hard to tell who is a good guy and a bad guy. The remaining real titans teamup with the snakes to try to defeat these mimics. Flying horses gett sot from the sky. This book is really not a standalone book and builds off the first and leaves many holes unresolved for the next.
the final Pegasus book takes things to greater extremes. It is now the universe that may be in danger. There are mutant titans that suck power. The only way they are defeated in the end is by having them suck too much power. In between, the goodguys go Wandering Earth and move a planet.
Titans is a sequel to the Pegasus series. The Titans and Olympians are at peace. the kids are all going to school. The book is much more lighthearted than the Pegasus books. It also as written intentionally as a multipart series. This book ends on a cliffhanger with nothing wrapped up. 
New deities come on to the scene in the 5th Pegasus book. Even after Emily promises to take her battle elsewhere, we still get a battle between Olympians and Titans right over Hawaii. (They manage to show up just at the "wrong" time.) This books gets a little more confusing and contrived. Pegasus is flying around the world to eventually get to Hawaii. There the fallen shard is protected by a Hawaiian god. However, there is another girl that shares the power with Emily and her "head-mate". This girl is a spoiled brat that wants everything. They eventually are able to defeat her and then join with her. The "super beings" also show up and banish the Olympians and Titans for misbehaving. Things get confusing, with some leaps in logic. But there are also some fun random moments with various gods exercising their personalities.
After going through many extreme stakes involving the destruction of worlds what's next? Time travel! On an architectural dig, a stone is found that causes Olympians to get sick and age. They need to go back in time to find it and restore peace. There is an CRU member that goes with them (and renounces the CRU.) Traveling on the solar stream also occurs. They need to prevent the Titans from destroying the Greek gods. They also need to make sure the gods are not youth, but. the proper age that they are remembered in history. Everything works out, but it is somewhat sad that the shared experiences are now missing from others. 
New conflict arises in the third Pegasus book. The CRU has cloned a bunch of the Olympians. When they see their clones, they just want to destroy them. The Olympians decide they want to destroy the earth. Emily is able to (too easily) talk them out of it. The most interesting part is the battle royale that takes place in Vegas, destroying a big chunk of downtown. Oops!
In the second Pegasus book, it is discovered that the bad guys from the previous book (Nirads) are not actually that bad. They are "goons for hire" who the Gogons are using to help conquer Olympus. And just to keep it fun, the other government agency bad guys are still in the way. Cupid is able to use his charm to help "defeat" the humans. However, the Gorgon's are a greater challenge that requires some alliances.
A daughter of a police officer and a boy from foster care find a flying horse. There is also a teenager that managed to survive after seemingly being pushed off a tall building. An "evil" Central Research Unit is trying to interrogate all of these people to try to find out more. After testing, they think the teen must be an alien. However, the kids have found out the truth. They are all Greek deities from Olympus. There has been a big battle and things are dire. However, if they find the special girl that Vestus has invested with the fire of Olympus they should be able to defeat the demons that have invaded. The girl ends up discovering that she is the special girl. She willingly sacrifices herself, but then discovers that rather than being killed, she has been made whole. All seems to be doing well. The book contains various life or death scenarios with people killed - yet the stakes never feel very high. It is also fairly easy to guess what will happen, but this probably works well for the target audience.
The epic battle for the security of the universe finally ends. Gaea has brought out her giants and has managed to get the blood needed to appear. The demigods have managed to get a statue of Athena in position to help them. However, it is not enough. There is also an imminent battle between Roman and Greek demigods. It is narrowly avoided. The leader of the attacking Romans ends up launching the crippling blow, which ends up being suicidal also. Leo also goes on a near-suicide mission with his mechanical dragon. His dragon gives him the "resurrection" position and they are able to meet with Calypso on the hidden island. The world is saved and the Greeks and Romans now live happily together... but Apollo is in trouble. There are new scenarios, but it is the same basic Percy Jackson that kids like.
The epic "kids save the world" quest continues. There is a quest through the underworld that culminates in an elevator ride up. Leo ends up on an island and falls for Calypso. There are ghosts of Roman legions that come out and fight against bad demons. There is a mind-cleared "Bob the Titan" who comes in at various times to help the kids. (Memory erasure seems to be a common theme in this series.) We also find out that the gruff satyr coach is married. The Romans and the Greeks are somewhat working together. There is plenty of rolicking adventure, though the book is longer than others.
The Greek and Roman demigods are together. They (barely) manage not to kill each other. They also survive competing love interests. They need to go on quests. One takes them to an aquarium in Atlanta holding a lot of mythical creatures. They barely manage to survive (even as one turns into a goldfish to save himself.) There is plenty of adventure and comedic relief as they discover more about what is going on, the weird condition of the gods and the differences between similar Greek and Roman deities.
