A book read solely for the sake of (maybe guilty) pleasure rather than for any complex plot, character arcs, or deep hidden meanings. These books are like candy: short, sweet for the sake of being sweet, and they bring happiness at the time of consumption. Hint: most cute romances fall into this category.
A close cousin to the candy book, cozy reads tend not to be too plot-heavy or action-packed, but they are more focused on characterization. These are the sort of books you can read with a hot drink and get sucked into a realm of comfort, nostalgia, or just plain good vibes. Cozy reads range from comfy romances or mysteries to whimsical fairytales, so long as they leave one feeling . . . cozy.
These books may be lacking in an overarching plot or simply don't focus as much on one, but they are character-driven emotional rollercoasters meant to explore human complexities, questions about life and love, and emotions in general. Or maybe the author just wants us to have a good cry and we got suckered in.
Buckle up, buttercup, because things are about to get epic. An epic read must contain a killer layered plot, three-dimensional characters with amazing arcs, believable world-building, and action/adventure galore with perhaps some romance or mystery thrown in.
