4.5 stars.

I'm so glad I finally read this. I'd been putting it off since it's middle grade and I didn't think I would really enjoy it. Somehow, it had gotten the reputation of a poor man's Harry Potter in my mind. I was so wrong. This book stands all on its own and though it takes on the same trope in a way, it stands alongside Harry Potter rather than needing to be compared to it.

Yes, there is some less mature writing since the intended age is younger, but it was still incredibly entertaining. I love the detail to the inclusion of the Greek mythology pieces and the somewhat flippant attitude of the writing made things both interesting and fun. The mystery of the book wasn't obvious, but there were clues along the way that allowed the reader to discern the ending if they paid close enough attention. This is written very well for the age group, still a somewhat challenging read but both entertaining and educational in a way. I will definitely be continuing on with the series.
