Need suggestion for books related to Sir Ernest Shackleton

Hi everyone,

I’m looking to read more about Sir Ernest Shackleton and his incredible leadership during the Antarctic expeditions. I found a couple of books on Amazon—Endurance and The Shackleton Way—but I’m not sure which one to start with.

Could you please recommend which book would be the best first read to truly understand Shackleton’s story and leadership style?

Thanks in advance!
