The Shane sister

15-year-old Eli Shane is just a regular kid from the suburbs, except for one thing: he comes
from a long line of Shanes, each of whom has made the journey from the surface to protect
Slugterra and the slugs that make the underground world so special.

When Eli visits his friend, Emily, or Em as he likes to call her, he teaches her basic skills
she'll need in slugterra, yet she doesn't know that much. She has a tazerling slug named
Ziggy, who keeps her company. Ziggy had somehow found her way up to the surface.
Now it's Eli's turn to be Slugterra's next Shane -- whether he's ready or not! Unfortunately,
the slugslinging tournament he enters to prove that he's ready, quickly shows that he's not! So
when word of this new Shane reaches the ears of the nefarious Dr. Blakk, he's not too
worried... yet.

When some weird bullies start targeting Emily, after writing to Eli about it, she heads to Slugterra earlier than she expected. This should be an adventure.
