What’s it about?

The story.

Five months on from the nightmare at Crater Lake, Lance is trying to be normal: new high school, new routines, and a mum who came home strangely well after being so ill. But the gang has drifted apart in the chaos of Year Seven, and Lance is mostly on his own when an explosion rocks Straybridge University and a test subject escapes the lab. As the town goes into lockdown, Lance and his new friend Karim start to suspect that his mother's miraculous recovery has a sinister source – and that the aliens they thought they'd beaten have learned, adapted and come back harder to kill. To stand a chance, Lance has to pull his fractured friendships back together and face an enemy straight out of their nightmares, on home turf this time. Jennifer Killick's Crater Lake: Evolution takes an already creepy monster and makes it scarier and fresher, keeping the trademark humour and heart while turning the dread up – wickedly smart sci-fi horror for readers who loved the first fright.

Fit check

Right for your child?

Where it lands by age

For confident 9-12 readers who enjoyed the first book; independent reading fits 9 up and it reads aloud from about 8 for children who like a scare. The heightened dread, alien body-snatching and a threat wearing a parent's face make it a poor bedtime pick and too intense for very sensitive readers.

Why it lands

Why they love it.

Why kids love it

The monster from book one returns smarter and scarier, right in Lance's home town, and this time it's hiding in his own family. The creepy moments hit harder, the gang has to rebuild before they can fight back, and the mix of terror and jokes never lets up.

  • Surviving danger
  • Friendship and belonging
  • The underdog winning
  • Breaking the rules safely

Why parents love it

Killick makes the follow-up scarier and cleverer without losing the humour or heart, and threads in the strain of shifting friendships as the gang start high school. Fast, funny and genuinely creepy – a reliable win for readers who devoured the first.

  • Quick to read
