up we go #5 Mystery Cache

The cache isn't at the above location but you can use it as a parking space.  

As the name suggests you need to climb for it.

This is based on the only connect missing vowels round.  

These are the titles of books of a single author.  

You will need to work out the book’s title and then find out where in the series it was written.

The Cache is found at:  N 51 A.BCD W 002 W.XYZ

A = THPLGRMFHT 

B = THVRGNNTHC

C = BRTHRCDFLSPNNC  - THCNFSSNFBRTHRHLN

D = THDVLSNVC 

W = THHLTHF

X = SNTPTRSFR 

Y = MNKSHD 

Z = DDMNSRNSM 

The Cache is small so you will need to bring your own pen.
