While I have enjoyed other books by EchoHeron, this one didn't quite live up to the expectations I had upon reading the jacket. Just focusing on the 5 patients and Nurse Cat may have lead to a boring book, but Heron took it to a metaphysical level by involving Gage, a blind newspaper salesman, and his visions that are transferred to Cat and it spoiled the book for me. I like that Heron gave background about her patients to explain how they ended up on Cat's ward and what they experience while in the hospital. However, even there, one of the patients is in a constant state of hallucination and he is always seeing a giant red set of lips and boyhood friend, though the friend made sense in that he was waiting to help the patient cross from the living to the dead.
I also didn't feel like the book progressed quickly. The character development was great and I loved Stella, the elderly lady on the ward who is there only because her nursing home kicked her out, and the relationship she and Cat formed. Cross, a famous author abused by her boyfriend, and Corky, a suicidal teenager prove good for each other's issues, though I don't know how realistic their interaction is. Add in Cat's two patients dying from terminal illness (plus the roommate of one, who is resigned to the same fate), and this is the strangest hospital ward I've ever known of. Perhaps in the early 90's when this book was penned, hospital wards were like this, but these days, every specialty seems to have its own wing of a hospital. Between the unlikely interaction scenarios and the metaphysical stuff, I just found the plot to be unrealistic and plodding at times. Heron did leave some mysteries unanswered until the very end which were enough to keep me intrigued and eager to finish.
I will read Heron's other books, as this was her first work of fiction and I have read at least one of her later books to know that she is a good author. Mercy just isn't her finest work.
