Book wise, I'd recommend The Big Print by nostr:nprofile1qqsypjyxzkns7qnxrylzsgh3h53e3sd86mq8auv24dr4mtkxdqlzjccpzdmhxue69uhhqatjwpkx2urpvuhx2ue0qy28wumn8ghj7un9d3shjctzd3jjummjvuhsz9thwden5te0wfjkccte9ehx7um5wgh8we30hu2ecz and I haven't read it yet, but I bet Bitcoin Is For Everyone by nostr:nprofile1qqswmnfq2k830kvnylvyrezc97dsqce343qppqrwlgpqaux5qpuwdkspz9mhxue69uhkummnw3ezuamfdejj7vwhrff is a solid intro.

Also, I'll shamelessly plug my own guide: https://keithmeola.com/bitcoin/bitcoin-is-for-everyone/ (I wrote and titled it before Nat's book 😛)
