Fortune's Fake Marriage Plan — Tara Taylor Quinn

Desperate times call for desperate measures…

Even marriage!

Single dad Jax Wellington's world turns upside down when his former in-laws show up in Emerald Ridge, Texas, demanding full custody of his beloved son. What better way for the wealthy rancher to prove his upstanding nature in court than to marry the daughter of one of the most venerable families in town -- for appearances only, of course? Kindhearted Priscilla Fortune is game to become Jax's temporary bride. But playing house with the closed-off cowboy leads to powerful sparks. Priscilla knew their arrangement was just for show. But she never dreamed that this make-believe romance might lead to the real thing: a child she adores...and the love she never thought she'd find!
