T. Kingfisher's Summer in Orcus
Ursula Vernon's latest under her T. Kingfisher brand (for her less kid-friendly stories--though I think this would be fine for older kids) is just as good as all of her other awesome books, so hooray! Originally published as a serial, this story centers on eleven year old Summer, with a very overprotective mother, and what happens when Summer encounters Baba Yaga and is granted her heart's desire. There are so many great characters here (you will be rooting for birds and trees galore) and I loved everything about it. There are a couple of typos (let me proofread for you, Ursula Vernon!!!!) but who even cares because this is great. Glorious, even. A/A-.
Full disclosure, Ursula Vernon did signings at a store when I worked there and I think she is super cool.
