Not sure if this one is going to be any easier, but I've been slowly going through Max Born's Atomic Physics after I picked up it used for really cheap. I like the way he goes through each step historically and presents quantum mechanics as a progression of discoveries based on what people were thinking at the time, which for me made it easier to reason about.
