Marry Your Baby Daddy — Maryann Reid

When their unassuming Grandma June dies, Giovanna, Keyah, and Fatima are shocked to learn she had saved a small fortune and has left three million dollars to them, her granddaughters. But there's a catch: each sister must marry the father of her children no later than six months after reading the will.
Piece of cake, right? Wrong! Each sister has a complicated relationship with her "baby daddy." Giovanna, a successful lawyer and a proudly independent woman, has no desire to marry Douglas---even if he makes her breath catch when he walks in the room and is a wonderful dad to their daughter. She's got a feeling that Douglas is keeping secrets. Keyah's boyfriend, Jag slipped a ring on her finger years ago but seems content to stay forever engaged. And Fatima's on-again, off-again relationship with Dune is filled with more ups and downs than a roller coaster. So why would Grandma June want her granddaughters to marry these men? Because sometimes Grandma really knows best. The clock is ticking. Will it be a countdown to wedding bells or disaster?
