Twinkle follows Tess Lee and Jack Miller after two years of marriage. Tess is a wildly successful and world-famous novelist. Her inspirational books explore our innermost struggles and the human need to believe that there is light at the end of the tunnel. Jack is a federal agent. After spending decades immersed in a violent world, a residue remains. As they both heal from past trauma, their epic love, fostered by their ability to truly see one another, has brought them true happiness. However, when an anonymous threat is made against Tess’s life, everything changes. Will they learn to lean on each other, or will they fall apart into the darkness? Their friends are along for the ride: Omar, Tess’s sarcastic best friend, who calls her Butterfly; the female president of the US who Tess visits regularly to discuss politics and bake cookies; Joe, Jack’s friend from the Bureau, who understands the sacrifices he’s made; and Bobby, Jack’s younger friend, who never fails to lend a laugh.
