 Okay, first of all, they weren't kidding about the explicit sex. I decided to give this book a go despite the fact that I tend to like my heat rating closer to warm than so-hot-I'm-blushing. After all, it's been on more shifter book lists than I can count. But it was also (no surprise) on the list of books for wallflower heroines. It doesn't really apply, in my opinion, as the heroine was formerly a wallflower but is no longer at the start of the book. 
 The Wallflower moves at a mad pace. It's not a long read. I was disappointed to find that the last 30% of the book was excerpts from other Samhain Publishing books. Actually, the first excerpt was from The Wallflower. Which is one of my biggest pet peeves ever. I wish publishers would take a little time to think that one through. I'm really curious to know how much extra work it would take to leave out an excerpt of a book at the back of the book itself. Or is it just laziness. Somehow, I think it's the latter. 
 Okay, right: The Wallflower moves at a mad pace. Events happen in a slam-bam thank you ma'am sort of way. And yes, I meant that double entendre. Max no sooner hears Emma's voice over the phone than he's meeting her in person than he's realizing she's his mate, turning her into a puma, taking her to bed and teaching her to be a wanton woman. There's hardly time for anyone to take a breath and, in all the mad rushing, important elements are left behind. Like plot and characterization. Max and Emma end the story where they began it. The only difference is that, by the last page, they're together. 
 Bell rushes Max and Emma into the bedroom pretty fast, but then it's revealed that Emma's a virgin. So, she's waited 25 years to have sex only to give it up without a second thought? That's...unusual. Why did Emma have to be a virgin in the first place? I don't mind virgin heroines, when they work for a story, but they mystify me when they don't. Especially novels with a great deal of erotic content. It's unlikely that a woman who has waited so long to go all the way will, after her first sexual encounter, suddenly be an expert in the bedroom. 
 The other thing that happens ultra-fast is the Emma's discovery of Max's werecat (Puma) nature. She accepts it with a minimum of disbelief. Also, we don't ever learn much about what it means to become a Puma, but all it seems to involve is eyes turning gold occasionally, the ability to shapeshift and an adherence to pack hierarchy. That's very much in evidence. Max also decides to make Emma a Puma without even telling her what he is. I didn't like that. At all. 
 My main feeling when I finished this book was that there wasn't enough substance to make it work. This is partly due to the length, but not entirely. Other authors have put a wealth of meaning into fewer words. I don't think I'll be buying the rest of the Halle Puma books, but I'd put free copies on TBR list. And, yes, that was a hint
