I really like Christine Feehan. This book was very dissapointing. The plot had promise. Nicoletta was a sweet heroine. The prose were good, and the medival Italy setting was an interesting change of pace. However, the plot flows like molasses in January. I managed to get half way through before I through the book down and went back to the 'Dark' series.

Ex Output:
Negative

As the author of [...] I recommend Your Child's Self-Esteem with all my heart.Until my book was out I told my clients, readers and workshop participants to read Briggs book. Although I treat tantrums differently, I find most of what Briggs said over 30 years agostill in line with my own guidance. She was way ahead of her timeand for the most part the book will give you everything you needto know about your child's self-esteem and more.
