While remaining my least favorite entry in The Dark Tower, this book is no less a masterpiece. A regrettably brief tale of Susannah/Mia's difficult journey to deliverance, it also portrays some of my favorite passages concerning Roland and Eddie. You can feel King's urgency throughout to reach the Dark Tower, and throw open the door at the top after thirty long years. Despite its unnecessary brevity and haste, this is thoroughly excellent. 5/5
