The Winter Mission: A Break System Gamebook

From BoardGameGeek:

The math says no. The season says yes. An impossible opportunity lures you from the streets of Toronto to the treacherous peaks of Switzerland in mid-December. You can't resist the target - something you thought was lost forever - but traps lie in wait. The enemy knows you're coming. Surviving alone may be possible, but it would take a miracle. Success demands more than skill and luck. You're going to need some allies. The Winter Mission marks the conclusion to the Break system series of gamebooks. With branching choices, dice-based challenges, and new crew management, this adventure will test every lesson you've learned, with every move you make. The dead of winter. The heart of Helvetia. A holiday heist to remember. -description from the designer
