From publisher blurb:
Agents and operatives working for the Mosaic Trust enjoy access to a secret weapon available to no other group, organization, or company. A mission team can, from anywhere in the world, place a call by computer or phone and request the help of a brilliant adviser known only as Hollow. Regardless of the time of day or their location, the mission team can ask for information, surveillance, or tactical advice. This resource has often proven the difference between a successful mission and a failed one. Although the Mosaic Trust restricts who has access to Hollow, the corporation has allowed some of their most trusted freelancer teams to call upon this resource. Such communications cannot be traced back to the Trust in any way. Even those employed by the Trust don’t realize Hollow works for their company.
