Honestly I would have to say no. It's worth a read, but it's not a must read and doesn't live up to the first. (Well, it's been a while since I read it I guess but I remember almost nothing from TWMF other than a nice front cover and a whole lot of disappointment.) Unless you want to get it out the way, but it's hardly a page turner.
I'd say check out You Die When You Die instead. I finished it last night- witty, bizarre, charming, vulgar. As you'd expect. The next isn't out until Feb 2018 but, judging by the ending to YDWHYD, the sequel is going to be Watson's craziest book yet.
