4 stars

The mystery continues. Strange things have been happening ever since the new unicorn family moved to Ponyville. A mysterious creature has turned up and now the Mane 6 are trying to keep the Cutie Mark Crusaders from new friends, Lilymoon and Ambermoon. Follow Sweetie Belle and her friends as they search for answers and solve the mystery of the Peryton Panic.

Well-written. This series is building so nicely. In this volume, we finally find out who The Pony is, deepening the overall mystery. While the Cutie Mark Crusaders solve the immediate problem in this one, there are still many mysteries to unravel.

Quite a few references to the first three books, so would recommending reading those before this one.

Such a fun series. Looking forward to the next book.
