The new O'Reilly book "Fundamentals of Deep Learning" by Nikhil Buduma (available on Safari for a while now) is good at the fundamentals- very clearly explained, nice diagrams. It it relatively close to the path of my Neural Networks classes (although those were 20 years ago). It necessarily shorter on detail in terms of the tricks of implementation that have radically improved performance of these techniques over the past 5 years, and might serve as a good read before diving into this via Goodfellow, Bengio, and Courville.
