Jeremy Fink and his best friend Lizzy must search high and low throughout the streets of Manhattan for clues to unlock the mysterious box he received a month before his birthday.

Uptight and straight-laced, FBI Special Agent Sarah Ashburn is a methodical investigator with a reputation for excellence--and hyper-arrogance. Shannon Mullins, one of Boston P.D.'s "finest," is foul-mouthed and has a very short fuse, and uses her gut instinct and street smarts to catch the most elusive criminals. Neither has ever had a partner, or a friend for that matter. When these two wildly incompatible law officers join forces to bring down a ruthless drug lord, they become the last thing anyone expected: buddies.

A young drug dealer watches as his high-rolling life is dismantled in the wake of his cousin's murder, which sees his best friend arrested for the crime.
