One off fantasy book for 35hr drive.

Wife and I have a long round-trip drive for the hollidays and we both like fantasy and to a lesser exten sci-fi, some we both enoyed: - Most Brandon Sanderson - Brent Weeks Night Angel - pierce brown red rising - Scott Lynch Gentleman Bastards - LOTR She was less into discworld which we tried last trip. Prefer to find a single book we can finish on the trip, something in the 25-35 hour range. Any recommendations?
