I am unbelievably disappointed by what's in the forest...
The cliffhanger in the first book, The Girl in the Garden, meant I had to read the sequel. Now I'm just frustrated. This could've been a five-star book, IMO, if the forest mystery had played out differently.
Outside of that, the writing isn't my favorite, but it isn't as terrible as the first few chapters of book one (when I almost DNF'd).
The emotional development and redemption arc of the FMC is well done, and I greatly enjoyed seeing her grow. The MMC was pretty static, though. Not that he truly needed to do anything other than exist, but still. It might have been more interesting if he had some flaws as well.
The duology is worth your time if you're okay with the mother of all cliffhangers in book one and some angst at the end of book two.
