I'm looking for comp titles as well as reading material. I'd like middle-grade fantasy that takes place in the contemporary world, preferably with some kind of secret magic going on. I want it to deal with issues of family, friendship, becoming a teenager, and first crushes, but in a non-preachy way. Examples of the sort of thing I'm looking for include Helene Boudreau's REAL MERMAIDS series and Sarah Mlynowski's MAGIC IN MANHATTAN series (which is sort of a MG/YA hybrid, I know). Girl protagonists preferred but not required. Brandon Sanderson's Alcatraz series also has a similar feel to what I'm looking for, though that's more portal fantasy.
Does anyone know any books that fit this description?
