I found this to be highly disappointing...
Personally the author should have left The Bronze Horseman where it was - as a sad ending. Even so I enjoyed Tatiana and Alexander to an extent.
However this book cannot be justified. I do not simply like books just because they contain the same characters as previous books.
For the first few hundred pages nothing happened apart from this:
Tatiana and Alexander argued.
She looked after her son.
Tatiana and Alexander argued then had sex.
They moved house and jobs and argued about it.
Nothing relevant. Nothing that kept the plot moving.
Alex turned into this controlling arse and seemed to want Tatiana to stay at home like a good little wife cooking him meals and looking after their son.
What exactly was the point to writing it? No point whatsoever. She should have left it at T&A as a happy ending (as it initially was - she said they lived happily ever after), rather then a mixed up troubled ending as this was. I really don't think she had anything more to say about these characters. She ruined them for me and I shall pretend this book never existed.
