"Cargo 3120: Ties that Bind by Aaron Walker Sr. is an action-packed, science-fiction military drama. The main character is Marcus, a mercenary who flies around the galaxy with his highly trained team of soldiers, undertaking dangerous missions for anyone willing to pay. When a mission goes wrong, Marcus ends up taking the fall so that his crew can go free. By the time Marcus is freed from prison, he’s decided to give up his dangerous lifestyle and return home to live with his sister and niece. His new, peaceful life doesn’t last long. When his former mercenary team finds themselves in trouble, Marcus is compelled to help them by transporting mysterious cargo on his spaceship. The mission seems easy enough until he finds out that two competing empires want the cargo and will kill anyone who stands in the way of their acquiring it.
Cargo 3120 is an enjoyable book to read because Aaron Walker Sr. has given us the two necessary ingredients for a great book - strong characters and a strong plot. Both of those elements thrive in this book. The cast of characters is unique and fully fleshed out. Marcus and his team of warriors are especially amusing yet loveable characters who are easy to root for. The plot moves at a fast and furious pace, providing lots of exciting turns along the way. The story also excels in all of the science fiction military scenes. Much of it plays out like a wonderful combination of The Band of Brothers and Star Wars. I highly recommend this book to readers of character-driven, high-octane science fiction."
