I think Dr. Robert Scaer, the neurologist's collection of books would be very helpful to everyone, and of course Bessel's book is a good companion to it. The Body Bears the Burden and the Trauma Spectrum are fundamental. The whole idea of the Trauma Capsule is easily understood and remembered by all I train. Dr. Scaer's breadth of work and patient load over 40 years looking at the differences between peoples abilities to recover provides an invaluable lense through which to see ACEs, PTS, TBI, etc.
