Book / resource recommendation - Microsoft Intune

Ok this is more to help fill gaps. 

We've had Intune training - theres plenty of elements I use day to day, but I am not in the office atm, so aren't involved in the Pc builds/rebuilds - theres instructions on how to do that if I was in the office  but I'd like to get a better understanding.

We've had training and I believe I have access for a good few months yet to the the training lab. But is there a recommended reading location/book that could be worth getting?

I mean I assume recommended reading is likely to be Microsofts own documentation - which is fine if thats the case. But sometimes its handy to have a book to call upon if theres gaps.
