Shopaholic takes Manhattan is again such a fun read and is very addictive. I don't recommend reading it before bedtime because if you're like me, you'll never end up going to sleep. Compared to the original novel (Confessions of a Shopaholic), this one is more serious, has more of a plot, but seems to be less funny.
If you've already read the first one, then this is must read. Because you've got to find out what happens next. Now that I've finished this one, I can't wait to find out what happens in Shopaholic Ties the Knot.
