I live in the U.S. and I can’t remember if I got a copy on Amazon or eBay. But I’m pretty sure it was one of the two. I think I paid $50 for it at the time (a few years ago, it was the third edition from 2015), but I got my money’s worth and more. Probably the best, most-well researched of the modern Titanic books. It’s considerably bulkier than most Titanic books, but after reading it you will understand so much more of nearly every aspect of the story. Good luck and keep your eyes open. Occasionally a decent copy will come up second-hand for reasonably cheaper. You can be cheated though so watch out. On the back of my copy, it said it was originally sold for £25 (I don’t know the current exchange rate and it changes frequently). I know that British pounds are usually more valuable than the U.S. dollars. Anyways, hope this helps.
