Montana sky - Nora Roberts

When Jack Mercy dies, he leaves behind a ranch worth twenty million dollars. Now his three daughters - each born of a different mother, and each unknown to the others - have gathered to hear the reading of the will. But Jack has one last surprise for them. Before anyone can inherit, they must live together on the ranch for one year.

For Tess, a sophisticated city-girl who just wants to collect her cash and get back to LA, it's a nightmare. For Lily, on the run from her abusive ex-husband, it's a refuge. And for Willa - who grew up on the ranch - it's an infuriating intrusion.

They are sisters ... and strangers. But when a brutal enemy threatens to destroy them all they must face the impossible challenge: to put their bitterness aside and live like a family.
