Lockdown at the Cosmo Vault

Lockdown at the Cosmo Vault is the fourth book in the Morph Explorers: Science Root Words series. These stories are designed to build morphological understanding through fast-paced adventure, not memorised lists. Root words are introduced through action and dialogue, helping readers link meaning to what the characters see, say, and do.

When a space-based morph-pulse strikes, Ben, Mia, and Samir follow LEX through a Lexi-Gate to the Cosmo Vault, a sealed morph zone once built to study the universe. But something inside has reactivated, and its security system sees the team as intruders.

Inside the vault, the crew faces spiralling tunnels, colour-coded traps, and a green laser maze timed to motion. When a purge protocol called auto-cide begins its countdown, the team must race to reset the vault's core before it shuts down completely.

Root words (cosmo, cycl, chrom, chlor, circum, cranio, and cide) are woven naturally into each challenge, giving children repeated exposure in meaningful context. A Root Recap and mission extension section at the end reinforce understanding and make the book ideal for classroom reading, small group work, or home learning.

With full-colour comic-style illustrations, short chapters, and inclusive characters, Lockdown at the Cosmo Vault adds a space-themed mission to the Morph Explorers series and helps readers unlock the power of root words one Gate-Key at a time.
