The Stargazer (Arboretti Family #1)

Michele Jaffe's sensual new novel Stargazer , set against the exquisite
background of Renaissance Venice, is the story of a brilliant and beautiful
doctor's daughter and the aristocratic rogue who crosses her path. Each
suspects the other of killing a well-known courtesan; when they're forced
to team up to prove their innocence, sparks fly. Jaffe is a Renaissance
scholar, so she knows the era -- and she knows the romance as well: this is
timeless historical fiction, with the kind of luminous heat that shines
from the romance shelves. Rated '4/5 - Explicit open door' for steam/spice/heat level.
