Blink #3

The Morlocks, servants of surveillance and murderous defenders of Blink, have found Wren, but the Eloi, a shrinking group of vigilant survivors, get there first and distort the endless, shifting walls to force Wren to navigate a maze of traps in order to evade the pursuing danger. Finally face-to-face with the final remnants of her origins, Wren gets the answers she's been obsessively seeking as to what happened all those years ago...but at a price she wasn't prepared to pay.
