The pacing of this book is breakneck! Which is good, because I quite literally couldn't put this down. Sometimes when plots flip back and forth between the present and the past, I get annoyed and distracted. Goldin works the breaks in at just the right times, leaving you hanging and breathlessly anticipating how everything comes together.
You know from the get go that there wouldn't be a happy ending for everyone. They mystery is what the group stuck in the escape room did to deserve their torture. Teasing out how each person in the elevator was tied together and what led to their predicament was so well done. This was addicting and kept my interest the entire read!
