In Blood Promise Rose is on her own, so is Lissa for that matter, Rose has set her self up for what seems to be a suicide mission. Dimitri is stronger, faster, smarter and older than Rose, now that he is a Strigoi there is no way she can defeat him, yet she packs her bags, hugs Lissa and heads off to Russia. It was great getting to know Dimitri's family and what a real Dhamphir's community was like. The time with his family helped Rose to heal his family accepted her, they treated her like a widow, not like a student losing a teacher she had a crush on.
Ok this is going to be really hard not to spoil the plot for you guys... the middle and end were so mind blowing, Rose is lost trying to figure out who she is and what she really wants in life. Meanwhile Lissa is losing herself slowly to the darkness as well as something more sinister.
