Long John Silver - Volume 4 - Guiana-Capac

The Neptune is gone, stolen by the Indian guide Moc, or maybe by
Guiana-Capac’s malevolent gods. The last members of the ill-fated
expedition—Silver, Dantzig, Livesey and Bonnet—are stranded in the
ancient city. Far from being broken, however, they will face head-on
what lies inside the gargantuan ruin, each for his own reasons:
revenge, duty, gold... or to rescue the beautiful Lady Hastings. For
Moc isn’t done with them, and he has plans for Vivian.
