Order one of these PCT guidebooks.
http://www.guthookhikes.com/2010/11/...he-pct-is.html Obviously Guthook, a thru hiker, has his personal desires in what he wants in a guidebook just like others including myself or you as a section hiker might want other things.
I agree with Guthook. The Wilderness Press books are not the best experienced thru-hikers option when doing cookie cutter PCT hikes but they do contain valuable info like sections that hold snow, water locations reliability(might be important since caches might be iffy in March), etc that I've found helpful for pre hike planning PARTICULARLY if hiking in heavy snow yrs or outside of typical time frames. I personally would not and would not rec carrying any of these books on a thru-hikes or section hike in their entirety or to solely rely on for maps or mileage way pts.
This is also popular.

I've seen this sold in several REI's(outdoor gear store in the U.S.) in Cali including one of the REI's in SD and the REI in LA. IMO I wouldn't want to be coming from Brazil and not have a guidebook in hand pre hike and not have Halfmile's maps perused thoroughly before hitting the TH for a PCT section hike.
For good free maps get Halfmile's PCT maps for the PCT sections you're interested.
