All Our Wrong Todays

This was an enjoyable time-travel story, though my thoughts careened all over the place while I was reading it. At first it really felt like Tony Stark and Howard Stark fanfic, emotionally distant genius inventor dad and wastrel son, which was fine, up to a point - then I began to get really tired of the narrator/protagonist. (And it's all told in first person, so we get every single thought in his self-absorbed brain.) Then the first bit of time travel stuff happens, and, oh wow! This is interesting! And fun to read! And there are other people around! But then, as always seems to happen in time-travel stories (because, first rule of time travel, YOU CAN'T GO BACK AND FIX THE THINGS YOU MESSED UP BY TIME TRAVEL), it all got twisty and complicated and wtf-y, and even the narrator/protagonist actually saying "trying to keep this time-travel crap straight in your head is a chore" didn't really help. So, overall: A for concept, B- for execution.
