In my review of Allegiant, I mentioned that at first I didn't feel Roth had a grasp on Tobias's 'voice'. I didn't feel that way after reading Four. Would it surprise you to learn that Divergent originally started out from his point of view? Four is a collection of stories which helps to explain just how Tobias Eaton transformed from a lanky teenager in Abnegation grays that no one noticed to a Dauntless front runner who couldn't be forgotten. I, for one, really enjoyed this quick read (clearly as I finished it in one day) and I felt like it delivered exactly what Roth promised: a glimpse into the mind of a character that kept all his cards close to his vest. I especially liked seeing the scenes from Divergent with Tris through his eyes. If you're a fan of the Divergent series, I think this is worth picking up and giving a whirl.
