If the YA drama “Sterling Point” has become your new hyper-fixation show, you’re not alone.Amazon reports that the coming-of-age series, from creator Megan Park, was the most-watched show on Prime Video worldwide since its Aug. 5 debut.

“Sterling Point” centers on 17-year-old Annie Jacobson (Ella Rubin, best known for “The Idea of You”), who was raised in New York City with her twin brother (Keen Ruffalo) by her adoptive father (Jay Duplass). But when the twins’ grandfather dies and they inherit his picturesque island, Annie sets out for Muskoka, Canada, to learn more. What, or who, she finds is Ramona (Amélie Hoeferle), a standoffish girl who looks just like Annie’s late mother and insists Gordon was also her granddad. The series unfolds over a sun-drenched summer as the two young women develop a sisterly bond while navigating all sorts of drama in the romance department (It wouldn’t be a YA series if there wasn’t at least one love triangle!) and more family secrets are revealed.

Variety’s review was a rave, with TV critic Aramide Tinubu pointing out how “Sterling Point” offers something “wholly unique and wistfully authentic” to the YA genre — populated by such hits as “The Summer I Turned Pretty,” “Off Campus” and “Every Year After” on the same streamer. What sets this show apart, Tinubu writes, is the depth of its exploration into themes of “grief, self-discovery and being brave enough to face the past.”
