Unfortunately I can't recommend the book. It's a fascinating subject, but ... Much/most of the book is devoted to what various Eastern Mediterranean civilizations were like before the Collapse of the Late Bronze Age. It's useful as an introduction so that you can get some idea of what collapsed, but it shouldn't be most of the book.

The treatment of the collapse itself is fairly shallow. I know the collapse is still mysterious and comparatively little is known about it, but that's why a book like this should be so interesting. Surely there is enough information to fill a comparatively short book like this. The ever mysterious Sea People's are mentioned of course, but other than noting that they weren't just one group and that the Egyptians defeated one group of invaders he says little. There is the usual "they may have been from here, or perhaps there" but it doesn't go into much detail about the different theories. The possible causes of the collapse aren't discussed much either. Basically it says "stuff fell apart and here are some examples". I know that much of this stuff is far from settled but discussing the evidence and arguments for various theories is a good approach. Talking about how new civilizations arose after the collapse would have been interesting too; much more than endless detail about pre-collapse civilizations like the Minoans.
