First, the suspense aspect of the story is well done and is interesting - it's about minors being involved in Internet pornography; battles over technology; a kidnapping, etc. A lot of romantic suspense titles nowadays would put nearly all of the focus on those plots, leaving a relatively scant number of pages for the romance. That's not true in this case. Alden interweaves both aspects of the story in such a way that readers won't feel short-changed by either of them.
As for the romance - it's hot. Ethan is pretty much the archetype for a romance novel hero: he's gorgeous, intense, and he has slept with lots and lots (and lots) of women. He's also got the requisite commitment issues, but they arise from a relatively surprising source, which I won't go into, as it could be considered something of a spoiler.
Toni, the heroine, is a character that is pretty likable. She's super-smart and focused, and she's tough; she's not someone who suffers fools gladly. She's also beautiful, but not in the stereotypical, petite, girly-girl kind of way. She prefers jeans, t-shirts, and sneakers over getting glammed-up (but when she does get glammed-up, Ethan has a very favorable response :) ), and she wears glasses. Plus, she's tall - nearly 6 feet. As I, myself, am I woman who is that height, I have to say that it was refreshing to read about a tall heroine for a change.
Toni also has her fair share of issues, mostly of the trust variety. Her feelings are certainly understandable and definitely make sense in the context of the story. However, her doubting Ethan's feelings for her does get a bit repetitive. That said, it does ring true that she would be reluctant to believe him at first, as the entire story takes place over about 5 or 6 days. She simply doesn't believe at first that people can fall in love that quickly. What was a welcome change of pace here, though, is that our commitment-shy hero does freak out a bit about falling for her so quickly and so completely, but while he struggles to reconcile that with how he usually deals with women, he winds up being surprisingly accepting of how he feels about Toni. He quickly becomes protective and possessive of her (but not in the uber-alpha way that tends to turn readers off), and though he realizes how fast all of this happens, that doesn't make him question what he feels.
As for the love scenes - they are plentiful, and they are hot. Ethan is a guy who enjoys talking dirty, and he indulges in that quite a bit over the course of the book. Sometimes dirty talk can be so over-the-top that it quickly plunges into cheese territory, but happily, that doesn't happen here. When Ethan becomes. . . descriptive, it only increases the steam.
All in all, this was a surprisingly enjoyable book. There were some repetitive parts, but even those didn't detract all that much from the story. The suspense is handled well, and the love story is written with some actual depth and a whole lot of passion. This was definitely a great read, and makes the reader anxious to see what happens with Ethan's twin brother in the series' next installment.
