I'm in love with the magic of Sydney Somers spellbound series.  Must be Magic is the fourth book in the series and it is hotter, sexier and  an amazing read.
The characters of Darby and Bryce show so many emotions that you can feel their pain, their frustration, and their love for each other and their families.  Darby is spunky and fun. Bryce is uptight, at first, then he finds out what really matters.
It is a wonderful modern fariy tale and you will enjoy the bumpy ride to get to a happily- ever- after.
Although you can read it first, I would recommend reading the series in order. 1. Say Your Mine 2. Don't Let Go 3.Whatever it Takes and 4. Must be Magice
