An Escape Room in a Book.
Format: Kindle
The literal definition of a page turner. Extremely difficult to put down. The story is like an escape room, a mystery, and a romance, all wrapped into one book. 📚

The fun continues!
Format: Hardcover
Escape rooms all around! Avery and three Hawthorne brothers, Nash, Jameson and Xander, create a game together with seven players. The winner gets a million dollars. The players are forced into teams as they are locked into different escape rooms, securing teammates. Gigi, Knox and Brady become a team; Savannah and Rohan are a team; Grayson, Lyra and Odette are a team. They must work together to escape their rooms and make it to the dock by dawn the next morning. Avery and the Hawthornes know how to figure out riddles and they know how to create difficult ones. Who will make it to the dock first? Likes/dislikes: I thoroughly enjoyed the riddles that the contestants had to solve. The mysterious watcher creates suspense and an added tension! Wonderful character development. Language: R for 47 swears, no f-words. Mature content: PG for gentle kissing. Violence: PG-13 for bloody death. Ethnicity: Rohan has light brown skin. Knox is white. Brady has ebony skin. Lyra has golden tan skin.
