From the back:
" a desperate call for help from a stricken archeological expedition brings Dirk Pitt to a sacred well, high in the Andes. What he discovers as he attempts to rescue two divers lost in the perilous depths, leads him into deadly confrontation with a band of ruthless art thieves, who plunder ancient sites for their precius artefacts.
Dirk Pitt`s extraordinary adventures take him to the fabled Lost City of the Dead, lead him in search of a Spanish galleon washed miles inland by a gigant tidal wave centuries before, and eventually set him on the trail of a fabolous hoard of Inca gold. But Pitt will need all his skills and tenacity simply to survive as he races to track down the sacred site-before the richest prize known to man is lost to the world forever..."

It is in the playground in front of Museggstrasse 20, Next to Spielplatz Musegg. Duck and look under the fountain. Look at the release zone'photo.
it is hidden so that only a bookcrosser finds it ;)
Good luck!!

Thanks for that clever hiding place!! Normally, people just put a book in a place visible for anybody, or even do not describe exactly where it is (eg. "railway station".
With your hint, it was not problem to find it :-)
Please be patient with reading it and writing my entry - I have several books waiting to be read.

Excellent book. Took me some days - and partly nights - to read it, but the story was worth it.
I will not keep it back long, but send the gold on his further travel. There are some public bookcases in Lucerne, I will soon choose one of them as a new place to rest for the book.

Thanks, biarstkular, for this entertaining lecture!
