The Stonekeeper by Kazu Kibuishi

When Emily, her brother Navin, and their mother move into an old family home, they expect to face a lot of cleaning and repair work. They don’t expect to hear strange noises from behind the basement door, nor for a tentacle monster to kidnap their mother!  It’s up to Emily and Navin to figure out how to set things right and save their mother’s life.

Princeless Volume 1 by Jeremy Whitley

I don’t know about you, but sometimes I get tired of reading about princesses who are just waiting for someone to save them.  In Princeless, Adrienne’s parents have locked her up in a tower that is guarded by a dragon in the hopes that a prince will come, rescue, and marry her.  But Adrienne is having none of that.  When she finds a sword under her bed, she decides that she’s going to save herself and other princesses who don’t really need someone to take care of them.
