Book One: Al Ewing and Javier Rodríguez follow up their acclaimed DEFENDERS: THERE ARE NO RULES series with a new volume and an all-new lineup, including none other than Loki, God of Stories! When Doctor Strange sends a dire warning from beyond the grave, Blue Marvel, America Chavez, Taaia (Galactus' mom!), Tigra and Loki assemble to defend reality itself! Plus, you won't believe who shows up on the final page!

Book Two: The adventure begins - in the path of the Beyonder? When Loki, Blue Marvel, America Chavez, Taaia and Tigra land rather unexpectedly in the Second Cosmos, they find their lives in the hands of its cosmic overseers - unless Loki can figure out the right trick to save them all.

Book Three: Loki's Defenders manage to escape the Second Cosmos and the Beyonder, but Taaia is grievously wounded in the process and none of Loki's or Blue Marvel's expertise seems to be helping. Enter - the Phoenix! But what is the price of a universal constant's aid...?

Book Four: DEFENDERS: BEYOND 4 On their quest to save reality itself, the Defenders have stared down the Beyonder and survived the scorching flames of the Phoenix, but now Loki and Co. must face their greatest threat yet -- themselves! The Defenders find themselves in a plane of possibility, where they are haunted by visions of the lives they wish they could have - if only, the dream weaver warns, they didn't have the others holding them back! Will they turn against each other? Or accept closing those doors?

Book Five: THE FINAL TRIAL OF LOKI! The final trial of Loki, America Chavez and the rest of the Defenders sees them entering... the one and only House of Ideas!
