Invisible! Power Surge

Nate's invisibility ring is going haywire — making his homework, his lunch, and even the family car vanish! When a mysterious girl named Sophie shows up wearing a matching ring, Nate discovers someone powerful is hunting for both rings. Can Nate and Sophie outsmart the collector before the rings ...

Six months ago, Nate Buckley found a chunky silver ring at a yard sale that turned him invisible. Now he was basically a professional. He could vanish mid-sentence, sneak extra cookies from the kitchen, and make his sister Emma think the house was haunted — all before breakfast.

Pretzel the dog was the only one who always knew where Nate was, which was annoying because Pretzel would sit and bark at thin air while Emma yelled, 'Why is Pretzel barking at nothing again?!' Nate's confidence had skyrocketed. He'd gone from 'the kid who once got his head stuck in a fence' to 'the kid who mysteriously appears and disappears like a ninja.' Life was perfect. Well, almost perfect. Lately the ring had been doing something weird — glowing bright blue at random times, like a tiny angry nightlight on his finger.
