Capsule

Two students from Brookwood High School mysteriously go missing on the same night.  The first is Peter Moon, a heartless pescatarian who bashes students from Brookwood on his blog, turning everyone against him. The second is the adored Kat Pike, an audacious girl desperate to boost her adrenaline. Three days pass. No leads. Indifferent to the disappearances, sixteen-year-old Jackie Mendoza remains immersed in her virtual world of video games and online friends. When a menacing app by the name of Capsule downloads itself onto Jackie's phone, she enters a game interlaced with reality.
A game threatening to erase Peter and Kat forever. Only Jackie can save them now-but Capsule is the most ruthless game she's ever played. Mel Torrefranca delivers a heart-wrenching thriller about unlikely friendships, bittersweet memories, and a never-ending search for answers best left forgotten.
