4 stars(Part of a series review that can be found here!)I read the Percy Jackson series around the time I'd started studying Ancient Greek and Latin in high school, and while the grammar lessons were a nightmare, I loved learning about mythology. I wanted to know all about the gods and heroes and mythical creatures - even when that learning involved translating ancient languages.The fun and original storyline is surprisingly accurate to the original myths (and my knowledge of Greek mythology was surprisingly extended) so I really enjoyed the references and modern adaptions throughout the series. Rick Riordan's world-building is just magnificent! It's not just that I'm always interested when it comes to mythology and that these are the stories I somewhat grew up with. Anyone who knows a little something about the myths and the gods will be pleasantly surprised by Rick Riordan's retelling. And anyone who doesn't will learn a lot about it.The Battle of the Labyrinth is probably my least favorite book in the series, which has a lot to do with the fact that I don't like Nico Di Angelo, who was such a big part of this story. I also wasn't really invested in some of the things our heroes ran into in the Labyrinth. Janus? Kampe? The flesh eating cows? They were all good scenes, but after The Titan's Curse was wasn't that invested in these stories.But the Labyrinth itself was really interesting! It kept building and expanding over the years and has all different types of architecture from different times. Really walking around there would be frightening, but the idea really appealed to me. I also enjoyed how Daedalus came into the story. The story of Daedalus and Icarus always really intrigued me, so I was glad to read about him as well.The entire series is just one long fun ride. Rick Riordan is witty and sarcastic (my favorite combination), but also created an amazing world, fast-paced story, brilliant conversations, big time fights and truly awesome heroes! And even though I'm trying to persuade my nine-year-old brother to read them right now, I still want to read them myself just as badly. There's just something about these books that makes me laugh and filled with excitement like not very many series can.Recommended to all fans of Greek mythology, great and loveable characters and an action-packed story. Also recommended for the younger audience.
