The Room at the Top of the Stairs

Book 7 in the award-winning Secrets of Redemption
Becca has always known something is off about that room. The one at the top of the stairs.
The one CB stayed in.
Yes, a terrible tragedy occurred within those walls, but there is more to it than that.
She had heard rumors about it, as well.
Rumors about something happening to anyone who stays there for long periods of time.
For over a year now, she had dismissed them as exactly that-rumors.
But now, Mia is the one living in it.
And Becca doesn't like the changes she is seeing in her ... at all.
