Book Two of the Lost Angel Series by Kate Bowyer
It is several years after the events in the small Idaho town. Ariel is now finishing up medical school. Those earlier days with Christian still haunt her, and things are about to get worse as strange events precede the start of her psych rotation.
Her first day at the asylum starts out with an injured ankle and upsetting the hospital's head of psychiatry. The doctor sends her to the local asylum, where the creepy head doctor makes each minute more uncomfortable than the one before.
She meets a patient whom she doesn't recognize but something about him feels familiar. Due to a case of amnesia, nobody has any idea who this man is, but Ariel is drawn to him which begins a series of events that lead to... well, we can't spoil the surprise now can we.
Committed is the second book in Kate Bowyer's Lost Angel Trilogy which is due out late 2016.
