Yes, the art is quite spectacular.
First book I'd reccomend for this deck: Tarot Mirror of the Soul by Gerd Ziegler. It really explains the cards in a very easy to understand way. It's the best place to start for this deck imo.
Then I'd reccomend next The Tarot handbook by Angeles Arrien. Very comprehensive, with lot's of info on spreads, year cards and other stuff.
Those 2 books would be a good foundation to start from I'd say. They both cover the thoth deck exclusively.
Ziegler also wrote another book on the thoth deck called Tarot Mirror of Relationships. Which is quite good as well and something you may want to consider, if you're going to ask relationship questions frequently.
The book of thoth by Crowley is amazing as well. but I wouldn't start with that. It's not written for the beginner.
