Eggs on Legs [EPUB ebook] 

Gems is a series of books written specifically for struggling girl readers. In this title Lara is tired of being second best next to her smarmy cousin Nathan. The town’s annual writing competition is coming up, but she has no ideas! If only something would drop into her head. Suddenly, she finds an ‘egg thing’ in the compost heap in her garden. When the egg starts making strange squeaking sounds, she knows she has to rescue it! In the dead of night, there are strange lights from the garden. There are two even larger egg creatures standing on the compost heap! Is this an invasion? Or do they come in peace?
