No Escape by Maren Stoffels

Following the success of her unputdownable debut, Escape Room, Maren Stoffels is back with a new standalone horror novel about a twisted game master who has no intention of letting their players go.
"You have been chosen to participate in a new Escape Room. You can bring one person. The one you trust the most. Your very best friend."
When Lexi receives an invitation to participate in a brand-new escape room, along with her best friend Tess, she's thrilled. They could both use the distraction after a recent tragedy.
But once inside, they learn that they must compete against one another.
What do you do when your best friend suddenly becomes your biggest adversary, and every choice you make puts her in danger? How far will you go to win?
