Publisher's Summary

Blast off on an adventure with the Space Cadets! From beloved children's author-illustrator Alex T. Smith, the bestselling creator of the Claude series and How Winston Delivered Christmas, comes a funny and fast-paced adventure through space!

With out-of-this-world narration and sound effects, Astrid and the Space Cadets: Attack of the Snailiens! is perfect for fans of Grimwood and Bad Guys, and for kids who are ready to listen by themselves.


Astrid Atomic, a six year old human person, goes to bed every night like every other six year old human person. But unlike many other six year olds she doesn’t stay there. The minute the lights are off and the coast is clear the Space Cadet siren goes off, her uniform goes on, and 5, 4, 3, 2, 1 - WHOOSH! - she blasts off on board the spaceship Stardust!

Along with her best pals Beryl, Professor Quackers and Zoink, Astrid is given her mission from The Chief - to clean up the Milky Way! But when a nearby alien is in trouble and with giant snaliens around, things aren't likely to go to plan!

Don't miss Astrid and the gang's next adventure in book two: Astrid and the Space Cadets: Race from Planet Peril!

What the critics say

Astrid and the Space Cadets made me BEAM with joy, full of OUT-OF-THIS-WORLD characters and illustrations. (Steven Lenton, creator of Genie and Teeny and illustrator of The Nothing to See Here Hotel)
Astrid and the Space Cadets! is just the kind of book I would have loved to read as a child. Alex’s wonderful witty writing is full of humour, adventure and I adore his fabulous character creations – The Snailiens! – genius! I’m just glad we don’t have any in our garden. (Jim Field, illustrator of Oi Frog! and The Christmas Pig)
