Just heard from my editor. Book two is a go! It's Rose's story, and the working title, DANGEROUS PURSUIT, is apparently out. They're going to try to tie the three books together with a "Forbidden" in each title. No idea yet what DP's new title will be.
I should have the proposal for book 3 ready at the same the time I turn in the slight revisions she has for book 2, so maybe I'll have more good news before the end of the year!
