Cosmic horror with a YA feel as two young friends, one a wealthy child prodigy, the other a close friend who works in a supermarket stock room, discover that the prodigy's new miracle power source opens holes into other dimensions where ancient godlike beings sleep, waking them and drawing their attention. There's a fair bit of angst in this as Nick ponders his friendship with Johnny, their relative status in terms of race, wealth and class, but there's secrets and betrayals ahead as they race across the world to stop the gods returning. It's well written, mostly fast-paced - some of the angsting drags things down a bit, and the central relationship is well-realised.
