Here is at least one time.
Revelation 3:5 'He who overcomes will thus be clothed in white garments; and I will not erase his name from the book (biblos) of life, and I will confess his name before My Father and before His angels.
biblos is actually used 34 times in the New Testament.
“Book of Life” does not refer to the canon of Holy Scripture assembled by the Catholic Church which Christians refer to as “The Bible.”
