Black Rose by Nora Roberts
I downloaded the audio book from the public library's OverDrive service.
I'll keep this brief, as Black Rose is the sequel to Blue Dahlia and is really almost a continuation of it. This installment of the In the Garden trilogy centers around Rosalind, the reigning Harper of Harper House and the founder/proprietor of In the Garden.
I enjoyed this book and I'm looking forward to the third and final one in the trilogy (Red Lily; I'm on the waiting list). I give a slight edge to Blue Dahlia, but this one didn't disappoint.
