Sometimes the useful thing about a collection is simply having the whole story in one place. The Mercer Files Complete Trilogy arrives November 3, gathering the three Mercer novellas into a single volume.

The Mercer Files Complete Trilogy by S.F. Baumgartner, with the invitation to start with the rig, follow the claim, and enter the vault.

The collection includes Black Gold Secret, The Lost Claim, and The Iron Vault. These are the three existing novellas, so readers who already own them can decide whether a collected edition would be useful. There isn’t a new fourth story to buy in order to finish the trilogy.

Each novella follows a different Mercer brother. Luke’s investigation in Black Gold Secret begins with an offshore catastrophe on the Gulf Coast. In The Lost Claim, Noah takes on a stolen claim in Australia. The Iron Vault brings Eli to the Pacific Northwest and a hidden archive. Together, those investigations uncover a conspiracy that has been protected for decades.

For someone coming to the Mercers for the first time, the practical appeal is straightforward: all three novellas are together. You can stay with the investigation as it moves from one brother to the next, whether you read them close together or leave yourself a break between stories.

Already read one of the individual books? Check which titles you own before choosing the collection. Having everything in one volume may suit the way you like to read, especially if you want to return to the earlier investigations while finishing the later ones.

The stories are clean action-adventure suspense, with family secrets and a slow-burn romantic undercurrent. The collected edition gives readers a convenient way to follow the full trilogy through its three settings and three brothers.

You can find the details on the Complete Trilogy book page or view the collection on Amazon. November 3 is just over a week away!
