Space Marauders — K.N. Kellum

Universally known as the best journier pilots in the Andromeda galaxy, fraternal twins Zebb and Ramsey set out on a dangerous mission to retrieve samples of a highly sought-after mineral, oky, used to double the speed of interstellar travel. Confident in their abilities, they land on the volatile planet Gorgion, where they encounter and join forces with journiers from a mysterious time-traveling galaxy. The friendship formed between the misfit crew is entertaining, intriguing, and altogether unexpected. Despite differences, they all share the same goal: to obtain the precious mineral and get out alive.
