i have all 3 books for tier 2. i only know this because i can see them at the vendor's "selling" booth in bright wall. however, i have no idea how to actually "read them" & apply to my dog. wth is up with this new way of handling inventory. this is easier? i wish i could just open my inventory & read the damn book already. sheesh. i know the game booklet says "Press up and the D pad when the book icon appears" but am afraid i "missed the train" (pun intended). do i really need to find new books now? for gods sake man!
