The Ultimatum — Susan Kearney

Dr. Alara Calladar needs a man...
...but she sure as krek doesn't want one.

If Alara doesn't make love soon, her cells will fail to regenerate and she'll die. Unfortunately, her only option is an enemy - Rystani starpilot Xander, her abductor...and a member of the race who has been battling hers since the beginning of time.

Xander issues an ultimatum: He'll make love to Alara only if she will use her psi-talent of identifying DNA to help him find the cure for the deadly Terran virus spreading across the galaxy.

Alara is trapped. She gives Xander what he wants - and gets when she needs. But Alara holds a pair of secrets: the more they make love, the more Alara's cells adapt to Xander's body, until the only person she can make love with is him - and the more time they spend together, the more Alara likes Xander.

When it seems that all the forces in the universe have aligned against them, can Alara trust Xander with her life...and her heart?
