La flecha de Poseidón (Dirk Pitt 22)

Poseidon's Arrow feels rooted in real history and legends, which adds depth but also complexity. I'm curious what inspired this blend and how much research went into it.

Some parts with detailed descriptions of underwater technology felt lengthy, but they also added authenticity. Was that balance intentional or just how the story evolved?

The international scope made the stakes feel huge, but it also made some parts feel a bit scattered. I'm wondering if that was planned from the start.
