To everyone else, they're inseparable. To him, they're best friends. To her, he's everything.

For years, Mila has poured her heart into letters for her future love. Dreaming of someone who could finally mend her broken pieces, she chased that feeling through heartbreak after devastating heartbreak. Now she thinks she's finally found it. She just never imagined it would be the man whose shoulder she'd cried on all these years.

But life has a way of forcing a hand. When her career is cruelly dismissed and her London flat floods, Mila has nowhere left to turn but to Samuel. Now, living together in his penthouse, the forced proximity shatters their decade-old boundaries. She can no longer deny that every secret line she ever wrote was meant for him.

Mila never meant to fall for Samuel, her best-friend of over a decade, whose world is miles from her own. Loving him means risking the most precious thing in her life: the friendship she already has. If she tells him the truth, she could lose him forever. If she doesn't, she might break her own heart instead.

Now, Mila must face the cruelest truth of all: the love she's spent her entire life chasing is finally within reach, yet it may not be hers to keep.

Dear Heart is a tender slow-burn, friends-to-lovers romance featuring lifelong best friends, forced proximity, unspoken love, yearning so deep it hurts, and the risk of losing everything for the chance at forever - from author Layla Cove.
