Stargazy Pie - Greenwing & Dart, #1

Magic is out of fashion. Good manners never are. Jemis Greenwing returned from university with a broken heart, a bad cold, and no prospects beyond a problematic inheritance and a job at the local bookstore. Ragnor Bella is a placid little market town on the road to nowhere, where Jemis' family affairs have always been the main source of gossip. Having missed his stepfather's funeral, he is determined to keep his head down.
Unfortunately for his reputation, though fortunately for several other people, he falls quickly under the temptation of resuming the friendship of Mr. Dart of Dartington, Squire-in-training and beloved local daredevil. Mr. Dart is delighted to have Jemis' company for what will be, he assures him, a very small adventure. Jemis expected the cut direct. The secret societies, criminal gangs, and illegal cult to the old gods--to say nothing of the mermaid--come as a complete surprise.
