SOLVED. Set on the Prime Meridian, Fantasy, Kid heart stops and is transported to other world [s]

I remember the plot vividly so the title isnt really a spoiler
The cover was a griffens eyes
Title was related to prime meridian somehow
There was a sequel
Definitely childrens book or ya
My edition had a weird cover that could be opened from the middle (like a prime meridian)

More spoilers below







Boy lays down on meridian, his heart stop, pace maker restarts it yet hes transported to other realm and theres a griffin and they go to a cool library thats really all I remember
It is definitely older than 3 years old
