The Blood of Olympus: The Heroes of Olympus, Book 5

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 House of Hades: The Heroes of Olympus, Book 4

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 Heroes of Olympus: The Demigod Diaries

The Heroes of Olympus: The Demigod Diaries by Rick Riordan

It is nice to be able to enjoy some Percy Jackson books where the stakes are not so high. Sure, there is the risk of death from monsters. But, "forgetting kiss anniversary" is more important than saving the world. The stories range among a number of topics. Some provide backstory for characters in the novels. My favorite was just a fun romp. Hermes asked Percy to retrieve his staff. They battle a giant to get it back. However, the giant is not familiar with how to use it and is just as likely to send out credit card receipts as he is to use a laser gun. The snakes also provide some comic relief. And in the end Percy resolves the "dating" issue with Annabeth. 

Rogue: The Paladin Prophecy Book 3

These days, it is all the rage to stretch out the last book in the series to a multiple movies. With Rogue, it feels like they really good have used more stretching out. The book starts with Will seemingly joining up with his grandfather on a quest to create super-humans. Later we learn that they have not really bought into Grandpa's story, and are planning to subvert his plans. That leads them to an adventure into the neverwas. Their powers seem to have been augmented, allowing them to always "know what to do". They eventually destroy the bad-guys machine that they would use to take over the earth. In the process, they run across one of their former friends who has teamed up with the "other side". They also rescue the "dead" angel and then return back home. It felt like a lot of details were missing from the story. There were also many enticing bits that were not explored. (I would have loved to see what happened when they finished with the bad guys and returned to face the "human baddies". How did time work? Was there any connection between the neverwas and their "mini-mes" on the computers?
There were many interesting avenues to explore. However, instead of going there, most of the book was just a series of battles with various monsters. The book used the excuse of "their powers getting stronger" to explain how they always "knew" the best path. However, even with that explanation, things were still too predictable. On the other hand, their "meanness" towards their former friend Brooke seemed to be way out of hand. The relationship with the "bad creators" also left a lot of questions. Why were there powers getting stronger? Why were they able to use these power to defeat the "creators", even though these powers came from the creators? There was some potential in this book. Alas, it was ruined by sloppy writing and too much focus on the action.

Alliance: The Paladin Prophecy Book 2

Alliance is the second book in a boarding school series. The kids all have their friendships and weird new things start to happen. Will West and his friends are trying to find out more about the secret society and beings that are trying to take over the world. The difference between good and evil starts to get fairly murky. They find new things out about people they know. They also begin to find other kids with powers. And in the process, love starts to kick in. Will is torn between two close friends who both have romantic attachments. The big "adventure" is the exploration of a castle next to campus and the unearthing of more knowledge of the past. The book answers a lot of questions, and then ends with even more questions. The writing is fairly fast paced, but does tend to telegraph future intentions a little too much, while at the same time having the kids just "know" things.

The Paladin Prophecy: Book 1

Will West is raised as somewhat of a nomad. His parents move about every 18 months to some new location. His father is a nuerobiology researcher and always is switching to new projects. They instruct him to live under the radar. He loves to run, but has to control himself to not be the fastest. He also intentionally does less than his best academically. Then one day, he accidentally aces an intelligence evaluation test and has a boarding school seek him out and offer a big scholarship. At the same time a bunch of secretive agents also try to catch him. He manages to evade them with the help of a taxi driver who later assists hi remotely. He makes it out to the boarding school where he makes friends and gradually learns more. There are bits of supernatural in the process. He learns that previous inhabitants of earth had gained too much knowledge and power and were banished. However, they are using manipulatable humans to get back to earth. He is to help get them back. His mother has been controlled by some of these bad guys.
He discovers that he has power to read other people's thoughts and to push images to computers. He can also run and heal super fast. Some of the other kids at the boarding school also have great latent powers such as photographic memory.
He seems to be able to identify the good guys from the bad guys long before we know which ones are which.
There is finally a big fight at the end and the kids discover who they really are. It all fits squarely in the "kids at a boarding school that will save the world" genre.
