Will someone tell my if my grammar is correct?

Hello, I wrote a paragraph below, and I like to know if the grammar is correct. I wrote this for Amazon.com for a review. Also, is it all right for me to post a short paragraph on this forum? The paragraph is below.

Priceless by Stephanie Meyer is a wonderful urban fantasy book. The story starts off with the heroine taking a missing child case. Her problems with the law increase as soon as she does take the case. The characters are excellent. Usually, I find the hero is a bit of a disappointment but not this time. Meyer main character is funny, tough, smart, caring, etc. Spoiler. One of my favorite scenes is of an FBI agent who has been hounding her for the disappearance of her sister. She finally gets fed up with his tirade, and gives him a big kiss. Her dialogue after she kisses him made me laugh. I could picture his face and hers as she went back to her vehicle. It was one of those gotcha moments. There were many good scenes, but I won't ruin the book for those who haven’t read it, yet. Meyer's characters are believable, and the book has a fast pace, good plot, excellent dialogues and surprises.
