Lies My Girlfriend Told Me by Julie Ann Peters

When Swanee passes away suddenly of a heart attack, Alix her girlfriend finds it a huge thing to deal with. Reliving memories, like how they met on a school ski trip, Swanees's sister, Jewell sticks around Alix to share memories with her and support her.

When she finds messages left on her girlfriend's phone from an LT, she doesn't know what to do. Half written in English and Spanish, she perseveres and finds herself uncovering a whole other relationship Swanee was having with Liana, a girl whom even believed herself to be in an engagement with her!

From a bad situation however, the two girls bond and enjoy a relationship together combined grief and love from the betrayal they've both suffered.

Both Alix and Swanee's parents are supportive of their relationship and that's such a good thing to include in a YA. The plot was very simple but effective as we see cause and after effects of one person's actions on lives of others. I found Joss to be a bit too dramatic a character in this book as a grieving sister I felt she would mellow a little whilst still harbouring some anger but that didn't happen.
