A cute retelling of the war between the Titans and the Olympians, told from Hades' point of view. A very quick read. I appreciated the short recap of the traditional telling (that is, the Zeus-centric version) at the end.
I will definitely read others in the series. Many thanks to @LibrarianRyan and @ravenlee for bringing this series to my attention. These books would be great with the Percy Jackson series.
