Welcome to Underline That!

Underline That is the podcast where we go beyond the page—exploring the things worth underlining in books, culture, and everyday life. Hosted by author and interviewer Stephanie Mack, each week brings a fresh episode—solo or with a special guest—full of curiosity, candor, and conversation.

Expect great books, bold talks, and big underlines! From book craft and faith to fitness and creativity, from chasing big dreams to embracing rest, this show invites you to reflect, laugh, and learn—always with another great book rec coming your way.
