Felix Spark’s little sister is a fixologist. Astrid
can fix cracked cups, broken toys, Felix’s thumb,
even Dad’s Harley Davidson when it gets swallowed
by a hole in the back lawn. But Astrid can’t fix
what’s under the house, threatening to destroy
the whole world - that takes a rock band, a didgeridoo,
an astrophysicist and a few thousand echidnas.
Get ready for an incredibly close encounter
of the third (fourth and fifth) kind....
