Meredith's family's annual game of assassin at Martha's Vineyard during a summer wedding is the perfect chance to honor her sister's legacy, and finally join the world again. But when she forms an alliance with a cute groomsman, she's at risk of losing both the game ... and her heart.

When Meredith Fox lost her sister, Claire, eighteen months ago, she shut everyone out. But this summer she's determined to join the world again.

The annual family vacation to Martha's Vineyard seems like the perfect place to reconnect. Her entire extended family is gathering for a big summer wedding, and although Meredith is dateless after being unexpectedly dumped, she's excited to participate in the traditional Fox family game of assassin that will take place during the week of wedding festivities. Claire always loved the game, and Meredith is determined to honor her legacy.
