Most Timeless novels are recommended for adults (22 years and up), while the pictured children's title is aimed at ages 4–8.

A recurring device is time-crossing or double-life storytelling—characters live in or wake up in different eras (often described as a 'time-crosser').

Most listings are available in paperback; some titles are offered in hardcover, and at least one is marketed as a hardcover deluxe limited edition.

The adult novels listed run about 368–400 pages, while the children's picture book is 32 pages.

The deluxe hardcover edition is described as having sprayed edges with stenciled artwork, a stylized dust jacket/cover, a shimmering cloth cover with foil stamping, designed endpapers, and exclusive bonus content.

The children's picture book is described as an Easter adventure and includes a "Make-Your-Own-Egg-Hunt Activity."
