Dr. Emma Walsh thought the graveyard shift at Mercy General would be her stepping stone to a brilliant medical career. But when she uncovers a pattern of suspicious deaths linked to the devastatingly handsome Chief of Experimental Medicine, she's drawn into a deadly game of cat and mouse. Dr. Sebastian Blake is everything Emma shouldn't want—brilliant, magnetic, and potentially lethal. As she investigates his secret 'Mercy Protocol,' Emma finds herself trapped between her growing attraction to the man who might be a murderer and her duty to protect her patients. The deeper she digs, the more she realizes she's not just fighting for the truth—she's fighting for her life. Will Emma expose the dark secrets haunting the hospital's corridors before she becomes the next victim of the doctor she's falling for? In these halls, every night shift could be her last. ⚠️ Author’s Note & Content Warning: The Night Shift Diaries is a very dark, high-stakes medical romantic suspense intended for mature audiences (18+).
