No. Just because these terms are mentioned together doesn't mean there is an association. Alyssa Eisner Henkin could be working in a completely different area of literature or other fields, and 'Trident Agent' in adult fiction could be something she has no relation to.
There's not enough information to determine whether she is associated with works about Trident Agent in adult fiction. She may have a connection if she has a diverse portfolio that includes this specific genre and topic combination, but we can't assume it based on just these words.
