THE CHILLING FINALE OF THE SPECTRA FILES TRILOGY The Wade House has been reduced to ash, but the dreams that plagued Becca Philips and Jason Brooks when they slept in that abomination continue to haunt them. After years of facing trans-dimensional monsters in the service of SPECTRA, a few lingering nightmares are to be expected. But when Becca starts singing in her sleep—an ancient song that conjures dreadful things from mirrored surfaces—she fears that the harmonics she was exposed to during the Red Equinox terror event may have mutated not only her perception, but also her voice. It’s a gift—or curse—that she shares with a select group of children born to other witnesses of the incursion. While a shadowy figure known as the “Crimson Minstrel” gathers these children to form an infernal choir, something ancient stirs on the ocean floor. And Becca, hearing its call, once again finds herself running from an agency she can no longer trust, into the embrace of cosmic forces she can barely comprehend.
