RaveThe Boston GlobeAn emotionally draining read, yet at the same time impossible to put down, it has all the makings of a modern classic. Donoghue’s inventive storytelling is flawless and absorbing. She has a fantastic ability to build tension in scenes where most of the action takes place in the 12-by-12 room where her central characters reside … Though Donoghue adequately captures the under-developed speech patterns, phrasing, and conceptualization of a kindergarten-age protagonist (not to mention one who has never had formal schooling), she is careful not to make Jack’s narrative voice cutesy or irritating...an innately intelligent boy, his curiosity about life outside of Room is what propels the story along.
