Isaiah Redmond and Isolde Eversea

⛔️ SPOILER WARNING! ⛔️

Does anyone know what happened to them and why they did not end up together? >!Did he cheat on her? Was it ever explained why she did not meet him by the trees? I know some of us have been begging Julie Ann Long for forever to write their story but she has been hesitant since it doesn’t end HEA.!<

I haven’t read the whole Pennyroyal Green series so i’m not sure if there are more clues in the other books.
