House of Thirteen by Andy Lockwood
Everything happens for a reason... doesn't it? Ren never put stock in sappy clichés... at least, not until the day she died. She's alive - again - but in hiding, adopted by the strangest of foster families: The Delaneys. Now, part of a sisterhood drawn together by unknown forces that spared her life, she begins a journey she could never have imagined: leaving her everyday world for one much more bizarre. It will be harder than she imagines, but alongside her newfound sisters, Ren will soon discover that everything does happen for a reason, but sometimes, those reasons are better left unknown.
