Lemon Dreams is a happy pony with a perfect life in Ponyville. There's only one problem - she thinks she's a lemon.

Is she really a pony-shaped citrus fruit, or is she just crazy? Does it even matter? When Lemon Dreams finds herself at odds with the ponies of Ponyville and pursued by a strangely familiar ghost, she realises she must discover the answers to those questions before it's too late.
