TEEN KILLERS AT LARGE

Signal Deere’s efforts to prove her innocence and hook up with trained killer boyfriend Erik culminate in a welter of hot snogging and blood-spattered betrayal in this trilogy closer.

Sparks winches up the suspense, pitching Signal into a desperate tangle as she frantically searches for ways to meet her thrillingly dangerous squeeze in secret; find out who’s stealing the evidence that she wasn’t the one who strangled and decapitated her best friend, Rose; and, most importantly, expose the threat of Wylie-Stanton, a secret algorithm that purportedly rates teenaged brains for potentially homicidal tendencies. But on the way to an improbably happy ending—and despite the throat cutting, computer and other hacking, mysterious black drones, high-speed car chases, assassin training, and revelations of evil corporate scheming to “fix” minors deemed troubled or dangerous—readers will get to enjoy some good old-fashioned romance. Series fans will enjoy seeing continuing plotlines playing out to reasonably tidy resolutions, and lines like “I claw at him, and he meets, then escalates my intensity, ladders racing down my tights as his fingers dig at my hips,” will appeal to fans of steamy prose in general. The leads are cued white, but names point to some intended diversity in the supporting cast.

Throbs and bleeds.
