Desire (Anne Hampson)

[from fictiondb:]

Kim Rosswell was young, beautiful, and desperate. Vidas Christou was wealthy, and determined that the child she carried bear the Christou name.

Kim knew she should have told Vidas the truth. There could not possibly be a child; another's lies had misled him. But the stakes were too high.

His proposal gives her a chance to save her father's life. That is something to cling to even after he discovers her deception--and she discovers that she loves her distant husband.
