Now I Rise | Kiersten White

Lada needs her brother Radu's subtlety and skill. But Mehmed has sent him to Constantinople as his reluctant spy. Radu longs for his sister's fierce confidence but for the first time in his life, he rejects her unexpected plea for help. Torn between loyalties to faith, to the Ottomans, and to Mehmed, he knows he owes Lada nothing. If she dies, he could never forgive himself, but if he fails in Constantinople, will Mehmed ever forgive him?
