Unicorn diaries

"Rainbow Tinseltail (called Bo) has never actually seen a dragon, but when things start going missing from Sparklegrove School for Unicorns all clues seem to point to a dragon pup called Scorch--but when Scorch does not return to the dragon caves, Bo and her friends become worried that he has gotten lost in the forest and they set out to find their new friend"--Provided by publisher.

Rainbow Tinseltail and the other students at Sparklegrove School for Unicorns are excited when a brand new unicorn, Sunny Huckleberry, enters the school, but Sunny does not know what his special magical power is, and the thought that he might not have any power at all is making him unhappy; Rainbow (whose power is granting wishes) is eager to help him--even though he does not seem to want her help.
