Section 01

Why Mangrove.

An origin

A mangrove survives because its roots run wide, not just deep. You cannot always tell where one tree ends and the next begins.

This imprint takes its name from that kind of root system: family, chosen family, work, memory, craft, and the obligations that hold a life together.

Every book under the colophon comes from real systems and real stakes. The thrillers understand controls and risk. The field guides understand plant-floor pressure. The memoir understands what happens after the incision closes and everyone else exhales.

Our roots run wide and deep — by blood and by choice.

The colophon

The mark is a tree with roots that carry the initials C, B, and W. The tree is the imprint. The roots are the reason.
