 Fiction by Colleen Hoover

Lowen Ashleigh is a lesser-known author on the verge of bankruptcy when she's offered a ghost-writing assignment that just might get her out of the financial hole. And bonus! it comes with a place to stay after Lowen gets evicted.

The job is to finish the book series for Verity Crawford, a popular author who suffered a debilitating accident, and the client is Verity's husband Jeremy. Lowen moves into the Crawford home (where Verity lies bedridden and unable to speak), and proceeds to fall in love with Jeremy. She also discovers some terrible secrets about Verity, and starts to think maybe the other woman is not as ill as her husband thinks. The whole thing is very Mr. Rochester. I mean, it would be if Jane Eyre had a lot of graphic sex in it.... 

The plot of this book was good, but it was awfully dark and smutty. It definitely held my attention.

I also read by this author: Confess, Hopeless
