Piper by Tasha Black

She signed up to give him an heir, but what he really wants is her heart.

Piper’s infertility sent her childhood sweetheart into the arms of another woman. Now she’s cashing in her credits at the local fertility clinic so she can do the traveling she’s always dreamed of.
But when the clinic offers her a secret third option, she can’t resist.
The plan? Act as a surrogate for an alien male, and have her own fertility restored in exchange.
The catch? She and the tall, dark and handsome alien will need to do it the old-fashioned way.
He’s wealthy. She’s poor. He’s set in his ways. She longs to travel. The only thing the two agree on? They’ve both made a terrible mistake.
Their pact is simple – convince the staff of the Midsummer Center that they’re trying their best. They’ll go their separate ways when it’s over.
All they have to do is manage not to fall for each other in the most romantic place in the known universe, where the admin, the staff, and the system’s most gifted AI are all working together to make falling in love (or at least in lust) completely irresistible.
