Nikhil and the Geek Retreat (Nerd Camp Briefs #1)

The award-winning Nerd Camp series continues with bite-size Nerd Camp Briefs!
Nikhil should be excited about the Summer Center for Gifted Enrichment winter retreat. It's supposed to be a weekend of learning and fun with his best friends, Wesley and Gabe. But his mischievous little sister, Monishah, is attending the retreat too, and it's Nikhil's responsibility to keep her from causing trouble.
Then Mo plans something that could get them both kicked out of Nerd Camp forever. What's the world's most cautious camper to do? Break as many rules as necessary, just to be safe.
