What's a good first textbook on Quaternions?

[MathExplorer]

Thanks to another thread I created, I already know what pre-requisite math subjects to study, and in what order to study them, before I'm ready to start studying Quaternions.

I'm just very curious about what specific textbook, would you folks on this forum recommend that I get to study Quaternions for the first time, when I'm finally ready for it?

Also, if you have a specific textbook suggestion on Quaternions, please give me the ISBN number of the book if you can. It'll enhance my ability to find the best deal on the internet for a copy of said textbook. :)

This is an open book from Springer "Quaternion algebras" by John Voight (not the actor Jon Voight, Angelina Jolie hehe )
https://link.springer.com/book/10.1007/978-3-030-56694-4

Perhaps a bit too advanced for a total beginner since it is a graduate textbook, but I kinda like it myself
