I've had the deal for a while (even started writing book two!) but the Publishers Marketplace announcement finally went live today!
A MURDER FOR THE BOOKS will be published this December (12/12/17) and then books two and three in July 2018 and early 2019. (Hopefully there will be additional books in the series if the first three do well enough).
And since that attachment (copied from Publishers Marketplace) is difficult to read, it says:
Victoria Gilbert's A MURDER FOR THE BOOKS, the first in a contemporary library cozy mystery series set in a historic town at the foot of Virginia's Blue Ridge mountains, to Faith Black Ross at Crooked Lane, in a three-book deal, in a nice deal, by Frances Black at The Literary Counsel.
