Hollow Code (Black Hollow Book 2)

One network. Two operators. Gideon Rhodes is off-grid, trusting no one but Felicity, a voice on the dark web. Until she pulls him out of a firefight and says three words: Darwin sent me. Lt. Zadie Noor needs him to crack ORACLE. The walls are thin. The stakes are lethal. Falling for each other is the one variable neither can hack their way out of.
