Weregirl

"Nessa Delphine and CM: three sisters together for the first time. Their father Daniel Host is a genius or a lunatic depending whose story you believe. His 30 000-acre "living laboratory" in rural Oregon is home to all of his creations including more than one genetic experiment gone wildy rogue. If you're Nessa unlimited forest means running as a wolf any time you want. But for her little sister Delphine the creatures of Daniel's world pose dire threats: especially the creature Daniel built in his lab many years ago from Delphine's stolen DNA. After the death of their mother Nessa Delphine and their brother Nate Kurland have retreated to Daniel's estate to recover and lick their wounds. But is Daniel's remote and perfectly synthesized world actually the most dangerous place they could be?"--Book jacket
