Night Shadow is the first of Cherry's psi/TFLAC books I read and was immediately caught up in it from the first page. Alex Stone and Lexi Stone are both TFLAC agents. Lexi is a by-the-book internal affairs operative and Alex does whatever he can to get his man. Lexi is sent on her first mission in the field with Alex with dual purposes, one as a TFLAC operative and the other as an internal affairs spy to investigate Alex to see if he is switching sides who is having erratic behavior because his powers keep fading in and out and the reasons for it are pretty shocking. Oh and did I mention Alex and Lexi are also lifemates. Another fantastic Cherry Adair book that has plenty of action and suspense.
