The Heroes of Olympus series by Rick Riordan is the sequel series to Percy Jackson and the Olympians. This series has 5 books featuring Greek and Roman mythology, perfect for fans of history and magic.
This series covers the story of seven Demigods, on their quest to stop Gaea, The Earth Mother. Unknown to most, there are 2 camps for Demigods, Camp Half Blood, in New York, and Camp Jupiter, in San Francisco. Both camps are unaware of the other's existence, with the exception of a few, such as Chiron, the leader of Camp Half Blood. Percy, Annabeth, Jason, Piper, Frank, Hazel, and Leo travel to the other side of the world, to Rome, Athens, and other, dangerous places. They face dangers, capable of killing them. They must fight Giants, Spirits, Gods, Monsters, and the Earth itself.
I can easily rate this series 5 Stars and give it an age rating of 8+ because despite the length, it is really easy to understand the book and the flow of the plot. However, my recommendation is to read the Percy Jackson series first, because it shows a lot of the backstory which is helpful information. I think this series is one of the must reads, at the top of the list. It is super fun to read, with lots of funny, witty moments. I just love the series, with every aspect, the plot, suspense, humor, characters, and detail.
Overall, this series is simply amazing, with excellent books about Greek and Roman mythology. They are full of adventure, suspense, and mystery. The humor and wit that Rick Riordan writes with is great. Every sentence is full of detail, making a vivid image in your mind, the Argo II, Camp Half Blood, and Tartarus. This will be a series that I will remember forever, and a series that will remain excellent for years.

Common Questions About The Heroes of Olympus
What order should I read the Heroes of Olympus books?
Read them in this order: The Lost Hero, The Son of Neptune, The Mark of Athena, The House of Hades, and The Blood of Olympus. And honestly, make sure you read the Percy Jackson series first — Heroes of Olympus is the sequel series and it'll be so much better if you know the characters going in. Both series are on BookVine.
What age is Heroes of Olympus appropriate for?
Heroes of Olympus is recommended for ages 8-10 (Grades 3rd-5th). If your kid has already finished Percy Jackson, they're totally ready for this one. The action is a little more intense and the cast is bigger, but it's the same fun style that Rick Riordan is known for.
Do I need to read Percy Jackson before Heroes of Olympus?
Yes, I'd really recommend reading Percy Jackson and the Olympians first. Heroes of Olympus continues storylines and brings back characters from Percy Jackson, so starting here would spoil some major plot points. Plus, Percy Jackson is amazing on its own — there's no reason to skip it!
How many books are in the Heroes of Olympus series?
There are 5 books in the Heroes of Olympus series by Rick Riordan. It's the second series in the Percy Jackson universe — after this, you can continue with the Trials of Apollo (5 more books) and The Kane Chronicles (3 books with Egyptian mythology). Rick Riordan really gives you a lot to read, which I love.
The Heroes of Olympus is recommended for ages 8 - 10 (Grades 3rd - 5th) with Lexile scores ranging from 660L to 690L.
