Tess Lee is a wildly successful and world-famous novelist whose inspirational books explore our innermost struggles and the human need to believe that there is light at the end of the tunnel. Jack Miller is a federal agent who has spent decades working in counterterrorism-a violent world that has left an inevitable residue on his psyche. Two years into their marriage, as Tess and Jack both heal from past trauma, their epic love, fostered by their ability to truly see one another, has brought them profound happiness. When an anonymous threat is made against Tess's life, however, everything changes. Will they learn to lean on each other, or will they fall apart into the darkness? In Twinkle of Doubt, the second Celestial Bodies Romance, Tess, Jack, and their chosen family explore the nature of doubt and the struggle to feel worthy of love.
