The Ceo Daddy Next Door (Harlequin Desire Book 2465)

He wants a mother for his child. She won't settle down. And now they're living together… 

After one disastrous date, reality TV personality Ashley George and devastatingly handsome British billionaire Marcus Chambers are roommates! When a fire destroys her apartment, Ashley leans on her Manhattan neighbor for help—and soon finds herself falling for the father and his baby. But despite their off-the-charts attraction, Marcus only dates women who would be suitable mothers for his daughter. His free-spirited neighbor is completely unsuitable. So why can't he seem to keep her out of his bed…and out of his heart?
