A very strange book. Part two in a series about a group of teenaged godlings who have been imprisoned in an English boarding school staffed with other mythological beings and gods. Apparently the first book was about them discovering their powers, and this one deals with them attempting to escape from the school/prison and discovering part of the role they were destined for (that the imprisonment was designed to prevent).
It's exciting and the world is interesting. It comes across as a lighter Gene Wolfe or more whimsical Tim Powers novel.
