Masha and her genius little sister Sunny are on the way to spend their vacation with their dad at a dude ranch out west. Masha is dreaming of horses and trail rides and doesn’t realize until the plane takes off that something is horribly wrong. Sunny , who booked all of the flights for the family, has booked them on a flight to Maine ! She re-routed them to MATH Camp! Masha is frantic and angry that Sunny has once again spoiled her plans. But Sunny has been pretending to be mom and dad , rearranging their vacation to one that she would prefer ( she hates horses). When Masha tries to make things right, the camp director contacts her parents and both are unable to come get them until camp is over. Masha must now attend science and math classes and stay at the vegan, gluten free camp for three weeks. As she begins to settle in and make friends, Masha realizes that she may just like it here. But then Sunny begins to act strange and Masha can’t figure out why.
This is the third book in the Sunny Sweet series. As in the other two books, Masha continues to get angry with her precocious little sister, and yet remain protective of her. Her character shows the real conflicts of living with someone so bright, and two sisters who are there for each other through the difficult moments of their parent’s divorce. This is a great series for the younger realistic fiction lover. This may be another series for fans of Judy Moody or Junie B. Jones. Well written with believable characters and emotions.
