Set against the glitz of 1930s Burning Cove, California, 'When She Dreams' follows Maggie Lodge, assistant to the enigmatic advice columnist 'Dear Aunt Cornelia.' Maggie hires private eye Sam Sage to fend off a blackmailer, setting off a combustible partnership. As they investigate an impersonator involved in psychic dreaming and a fatal conference, Maggie's own extraordinary dreams become a focal point. She grapples with abilities that attract dangerous attention, while both she and Sam are burdened by hidden pasts. Their hostile banter veils a growing attraction, but their secrets may cost them more than their hearts. Amid blackmail, murder, and the revelation of past betrayals, they confront a callous killer intent on vengeance.
