The Room Nobody Books by Sienna Vaughn

Forty rooms that exist — and yet don't. When auditor Sanela uncovers a discrepancy between inventory and booking system at the Meridian hotel group, she has no idea that behind the forty 'house reserves' lies more than a data error. Forty rooms that nobody books, in forty houses — all with the same flag. The deeper Sanela digs, the closer she comes to a truth someone has hidden very carefully. And the closer she comes to Rafael, who has his own reasons for looking. An atmospheric novel about numbers, trust and the rooms we keep locked from others. Meridian – Book 4.
