Dovetail by Karen McQuestion

From the bestselling author of Hello Love comes a spellbinding new novel of enduring love, family secrets, and mysterious death.
Joe Arneson's ordinary life is upended by troubling dreams of himself as a different man in another place and time. It isn't until he visits his estranged grandmother, Pearl, in her Wisconsin hometown that a startling connection emerges.
Drawn into his family's past, Joe discovers secrets weighing on the old woman's soul: the tragic death of her sister Alice a half century ago and its ripple effect on all who loved her. Digging into the events of that summer in 1916, Joe is convinced that his recurrent visions relate to Alice's untimely passing and to the beloved man she meant to marry. With the help of Kathleen, a local woman Joe's fallen for, the puzzles of the past start falling into place.
As uncovered truths bring Joe and Kathleen closer together, they also reveal a new danger. For Joe's dreams may be a warning—from one star-crossed couple to another.
