E. Aster Bunnymund and the Warrior Eggs at the Earth's Core!

If I thought the first book was great, I clearly wasn't prepared for this one to be even better. The world building is phenomenal, and the way new characters are introduced is great. My only complaint is that my copy didn't come with a book jacket for some reason...even though it seemed like it was going to when I bought it. This book was a little darker than the first, and I have a feeling that's going to be a prevailing theme throughout the rest of the series. I still think 9 or 10 is probably the target age for this, but the books are really great, so I think it just depends on your kids. Super excellent series! I can't wait to read the rest of it!
