This is Avengers Mech Strike (World of Reading, Level 1)

When the Avengers face an all-new, overwhelming threat, they're forced to engage in some creative thinking (and inventing) to level up their villain-fighting game. Each Avenger is given their very own mechanical suit (mech suit) that not only aligns with the look of their hero costume, but amplifies and complements their powers! Readers will be introduced to each hero's mech suit through an action-packed story perfect for fans learning to read.

This Level 1 Early Reader introduces the Avengers and their mech suits with simple sentences that are perfect for young readers.
