This book could have been great, but the author chose not to make it so. First I want to deal with the technical side, which is generally very good. The format is a bit like a computer game: each chapter title is a specific location. The descriptions are vivid and exact. They are not quite graphic. However, Lara's commentary when she is fighting can sometimes be a bit disturbingly blunt and callous. With that said, most of her commentary adds to the story and is in character. The general dialogue is good. The action scenes are excellent, and sometimes very creative.
The area where the book is flawed is the treatment of the story. The first quarter of the book is an excellent beginning: despite prodigious efforts, her friend is killed, and Lara is offered the chance to both help a (hopefully) good secret society reclaim its artefacts and get revenge. The last quarter of the book is the endgame of a battle spanning millennia, and is a pretty good conclusion to the story. The half the book in between is typical get the artefact, elude the bad guys tomb raiding. We know it's typical because the author says so right in the text. Whenever a scene is a standard type in the adventure genre, such as Lara gets the artefact and the bad guys take hostages, she points out in irritation that this is what always happens to her. She complains about clichéd dialogue too, even when she says it. Also, there are extinct monsters included pretty much because it's a standard feature of the games, with the barest justification for them in the story. Finally, Lara's attitude is that the tomb raiding is a boring slog she is forced to endure while she would rather be doing something else. Her negative attitude sucks the life out of the adventure.
This could have been an excellent book. The author intentionally made it otherwise. That leaves me feeling quite frustrated, much more than the enjoyment I got from the decent last quarter of the book. I cannot recommend this.
