Eva Price is the half-sister of Leanne Battersby and the stepsister of Toyah Battersby in Coronation Street’s Battersby/Price family setup.

Eva and Leanne

  • Eva is the biological daughter of Stella Price, who was later revealed as Leanne’s biological mother, making Eva and Leanne half-sisters.
  • This family link is why Eva’s return stories often describe her walking back into “family feuds” between her sisters Leanne and Toyah.

Eva and Toyah

  • Toyah is also treated as one of the Battersby sisters alongside Leanne, and in current storylines Eva is repeatedly described interacting with “her sisters Leanne and Toyah.”
  • In practical terms, Toyah is Eva’s sister/stepsister in the show’s family dynamic, and Eva often acts as the go‑between trying to keep peace between Toyah and Leanne.

Eva, Toyah and Leanne together

  • Recent episodes and coverage highlight the trio as a strong female unit, with the actress playing Eva noting that Eva, Leanne and Toyah are “strong women” who are “even stronger” together.
  • Storylines about their arguments over Nick and the Bistro revolve around them as three sisters navigating loyalty, betrayal, and reconciliation in the same tight-knit family.

TL;DR: Eva is Leanne’s half-sister through their mum Stella, and she is treated as Toyah’s sister/stepsister in the Battersby family, so all three are essentially sisters on Corrie.
