Investing in My Crippled Wife: My Duchess Makes me Overpowered

When the world writes you off, that's when the real reckoning begins. Emeric was branded Unblessed, a failed Awakening, a family's quiet embarrassment, a son with no future worth planning for. Isolde was once the Storm Mage, a legendary battle-mage, now left paralyzed and powerless after a catastrophic rift collapse. Cast off by their own houses, they're forced into a marriage neither family wants to acknowledge. Both families assume the pairing will quietly disappear. They're about to be proven wrong. On their very first night under one roof, Emeric awakens a hidden power, born from desperation. Every act of devotion he shows her gives him a reward. He awakens a new abiltity to protect his wife. Through his care, Isolde begins to heal in ways that nobody thought was possible. And Emeric, the boy who failed his Awakening gains the most dangerous ability. One that rewards you for fighting for those you love. Will they rise up stronger or will the status quo bring them down. — Description from novelcodex.org
