In many ways, the second London Underground book is a cautionary tale of the dangers of marrying someone you barely know. Kit and Tamsyn both go into their relationship wanting the same thing--money--but each has their own need for it and their own secrets to hide. Even as they're growing to care for each other, each constantly goes back to the earlier conversations they'd had (Kit telling her he wouldn't be capable of fidelity, for example, and saying that once she'd given him an heir they could both pursue their own separate amorous entanglements, for example) and keep their budding feelings to themselves rather than mention them to the other. And did I mention they have secrets? Honestly, at times reading this book was exhausting, watching them tiptoe around each other and knowing how each felt all the while knowing that they were hurtling themselves toward heartbreak... Through it all, though, both Kit and Tamsyn were sympathetic characters who you can't help but hope will somehow manage to find an HEA in spite of themselves. They do, thank goodness, but OMG does Ms. Leigh make them work for it! I have to admit that there is a stretch of the book where I wasn't Tamsyn's biggest fan--in getting upset at what she discovers about Kit she really does expose herself as something of a hypocrite, even taking her difficult childhood into account--but when we finally see the reasons behind what she's been doing for eight years (when she finally tells Kit!) I'll admit she almost had me willing to jump into the fray beside her...even as I hoped that there'd somehow be a different way to do things. Fortunately, Ms. Leigh had an even better solution in mind, giving everyone an HEA that was much more palatable than the one I was afraid we'd have to be happy with. Now all we need is Langdon's story! ;) (Counting on a Countess is second in the series but works fine as a standalone.) Rating: 4 stars / B+ I voluntarily reviewed an Advance Reader Copy of this book.
