While there is no book titled exactly "106 Geometry Problems" by Titu Andreescu with a 2021 publication date, it is highly likely you are referring to one of two things:
Both books are widely considered "useful texts" because they bridge the gap between standard high school geometry and competitive olympiad-level problem solving.
Here is a breakdown of why this text is useful and what it contains.
Given four circles each tangent to two neighboring circles and to two fixed parallel lines, prove that their centers are concyclic.
You cannot solve this without setting up a homothety or an inversion centered at a tangency point.
Absolutely. Whether you pay for the paperback or manage to find a legitimate preview PDF, the Titu Andreescu 106 Geometry Problems (2021) is one of the most efficient ways to transition from a geometry novice to a contest-ready solver.
However, remember: A PDF on a hard drive is worthless unless you open it, take out a pencil, and start drawing circles and triangles. The book does not give you skill—your deliberate practice with the book does.
If you are a coach or teacher, consider buying a class set. If you are a student, ask your school library to order it. And if you are self-studying, invest the $40—it is cheaper than one hour of private tutoring and will last you a lifetime of mathematical joy.
