The Door That Followed Her. The Mourningglass House, #3

The house is gone. The door followed her home. Evelyn Cross escaped Mourningglass twice. Now a matte-black door has appeared inside her Chicago loft-and behind it stands Lily, the little sister who died twenty-six years ago, grown into the woman she should have become. Then the doors begin spreading. Across the city, grieving people discover impossible rooms containing everyone they have ever lost.
Each memory gives the architecture another home. Each willing visitor makes the doors more complete. And at the center of the growing network waits Dr. Silas Wren, promising a world where no one has to say goodbye again. To stop him, Evelyn must enter the First Room and face Mourningglass at its most dangerous: not as a nightmare, but as the perfect life stolen from her. A living family. A future with Jonah.
Decades of happiness that feel too real to abandon. But a perfect home has one unforgivable flaw-and finding it may cost Evelyn every person she has ever loved. The Door That Followed Her is the devastating final installment of The Mourningglass House Trilogy, a supernatural horror series about haunted architecture, dangerous memory, and the difference between loving the dead and refusing to let them go.
