I loved The Terror, absolutely loved it ...The Abominable is not The Terror in Tibet, no matter what the cover and blurb suggests...
Brilliantly researched the first part of the book is an absorbing study of mountaineering in its Golden Age, the 1920s when tweed jackets and stout walking boots were the order of the day and anyone using oxygen was seen as a "rotter". The depth and breadth of Simmons formidable research is his hallmark and your enjoyment of this book will depend on your liking for detail...and lots of it.
I imagine many readers might not have the stamina for this preliminary journey. But if you do you are rewarded by a strong atmospheric and emotional reading experience. The middle third of the book is a uncomfortable reminder of how absolutely unforgiving Mount Everest can be to those foolish enough to attempt to climb her vertical slopes.
Lacking the creature set pieces of The Terror, The Abominable becomes a 'Boys Own' thriller/murder mystery with an action-packed finale near the summit. The big reveal was Disappointing with a capital D. A deceptive book in so many ways - it's not a sequel to the Terror, it's not about Yetis, the framing device is fiction and there are a myriad of deceptions in the story.
No it's not the Terror, it is altogether a different animal, but The Abominable shares the weaving of fiction with historical fact, characters you care about and a thumping good story...and lots of information about crampons.
