Al otro lado del espejo (Las investigaciones de Theo Cray nº 2)

The plot twists felt so well-timed and surprising. I'm curious whether this was planned from the start or evolved during writing.

The constant feeling of unease really kept me on edge, but I wonder if some readers might find it too intense or claustrophobic.

The way the narrative plays with what is real versus illusion was fascinating. I'd love to hear what sparked the idea to focus on these themes.
