Desperate Asylum by Fletcher Flora

A Brilliant Story Of Lesbian Love

From the back:

Lisa Sheridan—a beautiful woman, alone and unfulfilled, driven by unnatural desires… Avery Lawes— only half a man because he had never loved a woman…
They met, and each saw in the other a chance for escape. And so, in a frantic flight for normality, they were married. But they could not know the terrible depths into which their union would plunge them.
Desperate Asylum is the gripping story of a marriage made in Hell.
