Yesterday I finished Someone Comes to Town, Someone Leaves Town by Cory Doctorow.

The book is an urban fantasy, involving a main character to who is descended from a mountain, a winged girl, a brother who won't stay dead and a subplot about WiFi access.

It's a very good book, with a few problems. First, the ending is weak. It's too short and depends on a twist that doesn't fit very well with the rest of the book. Second, the book uses a flashback structure, shifting between the present day and the main character remembering incidents from his childhood. This works OK but at a point it shifts from a two pronged structure to a three pronged structure, adding flashbacks to the recent past, after some of the events that occur in the "present" part of the book. This is confusing and at times it is hard to tell whether a given chapter takes place before or after an earlier chapter.
