Weaknesses: This almost needed a list of characters and their respective clans at the beginning. The fact that there were six clans but five elements caused me some confusion. Wasn't keen on the theme that love is important, since loving people just means that eventually, they will disappoint you, but the target demographic doesn't know this yet.
This is probably one of my favorite of the Rick Riordan Presents titles, and I'll purchase it, and it will be popular with readers of DasGupta's Kiranmala series, Rivera's Cece Rios and the Desert of Souls, Alston's Amari and the Night Brothers, and the upcoming Pahua and the Soul Stealer by Lori M. Lee. This is no doubt going to be a series!
