Moonspear where all the children left without a trace, only to come back as pure as gold

Alya wasn't quite tall enough (or, perhaps, Galaxy was no longer quite short enough) to hold the bone out of his sister's reach. When Galaxy proved this by swatting at the prize, Alya began turning in frantic circles, trying to keep the bone away from her smaller sister. At first, she tried to growl back, but it quickly turned into a breathless laugh.

She switched directions when the bone was jarred almost painfully in her mouth. She did not know if it had been another swat from Galaxy or just her own clumsiness, but she didn't let that bother her much.
