Book Of Secrets — D.F. Hart

Book of Secrets, the second book in D. F. Hart's Vital Secrets series, brings back Bella Amsel, Nathan Thomas and Max Jones, and introduces new characters into the series as well. Bella and Nathan have survived the aftermath of a decades-old hatred come to fruition, and a face-to-face encounter with Bella-obsessed psychopath Mikel Metzger - who lies comatose after Bella shot him in self-defense. But Bella and Nathan didn't make it out unscathed - and healing from the nightmare is put on hold when Mikel regains consciousness, escapes the hospital, and enacts a horrific plan to claim Bella for his own.

Meanwhile, Nathan's sister Faith finds herself inexplicably drawn to Rick Conner, the retired US Navy cryptologist that's moved in down the block. And when Max Jones comes seeking Rick's services as a top-notch codebreaker, Faith realizes that their personal and professional lives will unavoidably intertwine.
