Tell Me Softly by Ron Mercedes

This book follows Kamila Hamilton, whose life is disrupted when
childhood friends Taylor and Thiago return. Years earlier, an affair
between their parents contributed to a fatal car crash that killed the
brothers’ young sister and shattered both families. Now Kamila is
caught between forgiving Taylor and resentful yet intensely attracted
Thiago amid family turmoil and toxic relationships.

This book’s main concerns are; alcohol, drugs, dubious consent
(school employee/coach-student sexual relationship/power
imbalance), explicit sexual activities/nudity, patently offensive sexual
content, pervasively vulgar content, profanity, prurient behaviors,
rape/sexual assault (attempted), self-harm, and violence.
