Winners, Losers, and Champagne Kisses — J.B. Trepagnier

The angels are here, but we don't know what kind of choir we're dealing with.It's what we wanted, but Kat has had dealings with them before. There are nine choirs of them. Some are peaceful and can be reasoned with. Others are rather stupid and violent. There's supposed to be a choir devoted to policing the stupid violent ones, but they all live in a different realm.We need the angels to convince the humans that we're not their enemy. We just don't know which kind are currently falling from the sky.
