My Best Friend’s Ex by Shannyn Schroeder

It’s not often that tragedy leads to happily ever after. But it’s not impossible either…
No one told Trevor Booth that parenting teenagers was like riding a roller coaster through a wildfire…during a natural disaster…in hell. That’s something he learns when he becomes a single dad overnight. Fortunately, his ex-wife’s best friend is there to help. His completely inappropriate attraction to her, however, is something he’d have to learn to deal with on his own…
Callie Larson is devastated. Watching two children she loves like her own suffer the loss of their mother is unbearable. She knows helping Trevor adjust to his role as a full-time parent is the right thing to do. But helping him does not include having a forbidden affair with him… or falling in love with him. At least, that’s what she keeps telling herself…

Can Trevor and Callie find a way to pick up the pieces and move on together—or are their emotional scars just too deep to ever heal properly?
