Signals route in a guidebook?

Heading to Tuscon and was looking at doing this and wondering if it is in a book yet? I know it's pretty new.

Thanks 

It’s only on Mountain Project, to my knowledge. Most of the modern, recent routes in that canyon are only online. Older routes might be on MP as well as in the old Kerry guide. 

Luckily, the mountain project page is pretty good. It's a little bit thought to find but you'll get there. Between the detailed description and the comments it's better info than you'd prob get from a guide book. 

I mean, what more could you want beta-wise? FWIW that would not be my choice for a visiting climber. It's certainly worth doing as a local or if minimizing drive time is highest priority but the classic climbing of that grade is in the Stronghold. YMMV.
