"B" Is for Bullion continues the series with a dangerous journey to recover a missing ship that's loaded with gold.

When the ship disappears in the Sea of Okhotsk, Fiona's parole officer illegally releases her from prison so she and the Alpha Adventures team can locate and recover the missing gold. His stake in this case is personal. The catch is, the Alpha Adventurers have to act fast before anyone discovers that Fiona's on the lam. If they don't quickly succeed, she'll have to return to prison.

With these high stakes, Travis worries that Savannah won't be working with him on this case. Instead, his two co-investigators are Fiona, a loose cannon with a penchant for trouble, and Thyri, who has a keen business mind, but no investigative skills. Travis knows he must be out of his mind to go on a mission with these ill-equipped Alpha Adventurers, but the payout for a successful recovery of the gold is a strong incentive to accompany them.

The plan for infiltrating the tight security of the shipping company is that Travis, Thyri, and Fiona will pose as WSJ reporters. Their first stop is the Multimetal headquarters in the Russian port town of Magadan. When they arrive at the press conference, they compete with other reporters for interviews with the spokesperson of the company. However, useful information is not forthcoming.

When Fiona unexpectedly deviates from the mission plan to do some covert environmental activism with a new acquaintance, Thyri, Travis, and a mysterious Russian woman named Bianca rush to retrieve Fiona from a remote site before she gets arrested again. Or worse.
