Adopted by Cupquake?!

This book is about a big Ihascupquake fan named Sarah who gets adopted by her! Sarah was just a ordanariy girl that was left at a random persons doorstep after her mom could not care for her anymore because she is part of the government and for her own protection she had to move from the U.S to Australia and she had to change her name and she could not bring anyone what so ever with her and that random person was Cupquake! And I know that that's not really "adopting" when your left at somewones doorstep but I can't really come up with a better title so to see what happens and learn more about Sarah you better read this! Ps. Only if you want to read this
