Anyone who has read the 10th Circle know the hidden message? It's by Jodi Picoult?

Question

The comic book pages have hidden letters in them. 86 total. Those letters spell out a quote and the author of the quotes name. I can't figure it out!!

I have 83 FOR SURE letters and 5 possible letters. NOHTINIGESASIERTHANSEDFCEITFROWHATEACHMNASIWHESTHAHTAELSBELIEVESOBTETEUREDOMTSNHESE The other letters (that could just be a shadow, I just wasn't 100% positive about them) LLEAM

The message is a phrase that summarizes the story plus the author of the quote's name. The letters are NOHTINIGELASIERTHANSEDFCEITFROWHATEACHMNASIWHESTHAHTAELSBELIEVESOBTETEUREDOMTSNHESE and the alternate letters that may just be a shadow are LLEAM

It would be helpful to us and also great fun for many of us if you would write down the hidden letters ... I am sure someone on here could figure it out.

Here's amazon.com explanation of the book

Amazon.com
Bestselling author Jodi Picoult's The Tenth Circle is a metaphorical journey through Dante's Inferno, told through the eyes of a small Maine family whose hidden demons haunt every aspect of their seemingly peaceful existence. Woven throughout the novel are a series of dramatic illustrations that pay homage to the family's patriarch (comic book artist Daniel Stone), and add a unique twist to this gripping, yet somewhat rhetorical tale.
Trixie Stone is an imaginative, perceptive 14 year old whose life begins to unravel when Jason Underhill, Bethel High's star hockey player, breaks up with her, leaving a void that can only be filled by the blood spilled during shameful self-mutilations in the girls' bathroom. While Trixie's dad Daniel notices his daughter's recent change in demeanor, he turns a blind eye, just as he does to the obvious affair his wife Laura, a college professor, is barely trying to conceal. When Trixie gets raped at a friend's party, Daniel and Laura are forced to deal not only with the consequences of their daughter's physical and emotional trauma, but with their own transgressions as well. For Daniel, that means reflecting on a childhood spent as the only white kid in a native Alaskan village, where isolation and loneliness turned him into a recluse, only to be born again after falling in love with his wife. Laura, who blames her family's unraveling on her selfish affair, must decide how to reconcile her personal desires with her loved ones' needs.
