Clowns from Outer Space [EPUB ebook] 

Ella can’t wait to celebrate Tia’s birthday. But when Ella arrives at the party, there are clowns everywhere. Ella does not like clowns, and these clowns seem extra creepy and a little secretive. Just what are these clowns up to? With short chapters, easy-to-read text and enhanced back matter, Boo Books deliver just-right frights (without the sleepless nights) for the earliest readers.
