Goblin Secrets, by William Alexander:
The combination of steampunky clockwork technology mixes well with the sense of real magic—my favorite mix of the two was in Graba, a Baba Yaga-ish witch who has clockwork chicken legs (as well as the aforementioned moving house)—and as in a lot of old-school children's fantasy, there are genuinely dark and scary bits as well as moments of joy and wonder.
Nothing Special, by Geoff Herbach
Shadow on the Mountain, by Margi Preus:
There's a wonderful balance between Espen's Resistance activities (along with the knowledge that if he's caught, his family will be punished for his actions); his younger sister's interest in his activities, which ultimately leads to her own direct involvement with the Resistance; the split that occurs within his peers between those who join the Resistance and those who join the Nazis; and his own coming of age and burgeoning romance.
