Blending families takes work — love makes room for everyone.

Twelve-year-old BFFs Ginnie West and Tillie Taylor are matchmaking geniuses. They’ve maneuvered Ginnie’s widowed dad into proposing to Tillie’s divorced mom. Operation: Secret Sisters is practically a done deal!

Until Tillie’s lousy-excuse-for-a-father returns after six years. Too bad “lousy dad repellant” doesn’t come in a can. He’s sober and determined to make amends, but Tillie wants him gone. If he stays, “Operation: Secret Sisters” may need to be renamed “Operation: Not Gonna Happen.”
