Best Work books for Unity

Good afternoon.
Can any of you guys/girls recommend any physical work books, to start/study Unity? I have a few Udemy courses and YouTube tutorials, but seem to retain more with actually hard copies. I appreciate any advice on this matter.

Thank you,

 

I think if you search book as keyword on the forum, you will find few recommendations from people. They are pop in every so often here on forum.

Problem with books is, unless they focus on general aspects of programming or theory, they quickly become obsolete, in terms of evolving Unity. Not to say, that you can not use older Unity version. But many of them just contain, what is on internet. At least many internet resources has comments from people, which allow for corrections, if applies.
