The Haunted Valentine (A Lin Coffin Mystery Book 7)

This is book 7 in the Lin Coffin Mystery series from USA TODAY Bestselling Author J A Whiting.
Although the main mystery is solved in each story, the books should be read in order for the most enjoyment as story threads run from book to book.
Lin and her cousin, Viv, stop into a gift shop in Nantucket town and while browsing, Lin sees an antique Sailor's Valentine.
The valentine, made of tiny beautiful shells, pulls at Lin and she decides to buy it and bring it home.
At times, the object feels hot to the touch and sometimes the shells illuminate and dim in a sequenced pattern. Once in a while, the valentine makes appearances outside the house in places Lin happens to be. A ghost pays a visit, but Lin has no idea what he wants from her or what his link might be to the sailor's valentine. With the help of her boyfriend and her cousin, Lin works to solve the mystery of the haunted valentine.
This story has ghosts and some mild paranormal elements.
